[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a document processing apparatus and method for outputting evaluation information for performing understanding evaluation on a user's document based on words in the document.
[0002]
[Prior art]
Conventionally, a document selection technique for selecting a document including desired contents from a plurality of documents is known. As such a document selection technique, for example, a keyword representing contents is given to a document in advance. In addition, a keyword search method for receiving a keyword related to a desired content from a user and selecting a document to which the corresponding keyword is assigned, or an arbitrary content related to a desired content from a user without giving a keyword to the document in advance. There is a full-text search method that accepts a word and selects a document containing the word by searching the full text of the document.
By using this document selection technique, it is possible to select a document including the content desired by the user.
[0003]
[Problems to be solved by the invention]
However, the documents selected by the keyword search method and the full-text search method described above include documents that are too difficult for the user or do not contain new content for the user. There is such a thing.
Whether or not the document is suitable for the user cannot be determined unless actually reading a part or all of the document.
[0004]
On the other hand, in the document search method and apparatus described in Japanese Patent Application Laid-Open No. 8-235204, the difficulty level is set for the document, and the understanding level for each field is set for the user so that the user can understand. A document selection technique based on difficulty level setting in which a document having a difficulty level corresponding to a degree level is selected is described.
[0005]
However, even with the document selection technique based on the difficulty level setting, it is impossible to determine whether or not the document contains new information unless the user actually reads part or all of the document.
In addition, it is difficult to select a document with a difficulty level corresponding to the user's level of understanding. It is difficult to respond to a detailed level of understanding that cannot dynamically respond to changes in the user's level of understanding. It is difficult to set an appropriate level of understanding according to the knowledge of individual users. For example, it is difficult to set the level of understanding level of users and the difficulty level of the document itself. A document corresponding to the user's level of understanding is not always selected appropriately.
[0006]
The present invention has been made in view of the above-described conventional circumstances, and provides a document processing apparatus and method capable of outputting evaluation information for performing appropriate understanding evaluation according to a user for a document. It is an object.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a document processing apparatus according to the present invention is a document processing apparatus that outputs evaluation information for evaluating a user's degree of understanding of a document based on words in the document, A phrase storage means for storing at least one of an understanding phrase understood by the user or an ununderstood phrase not understood by the user as an evaluation phrase, and an evaluation phrase detection for detecting the evaluation phrase from the document to be evaluated Means, evaluation word information creating means for creating evaluation information related to an evaluation word composed of at least one of the evaluation word detected by the evaluation word detection means or the appearance degree of the evaluation word, and evaluation related to the created evaluation word Evaluation phrase information output means for outputting information.
[0008]
Here, the phrase may be a word or a group of a plurality of words, or may be a word of a specific part of speech (for example, a noun) or a group of a plurality of words.
Further, the degree of appearance includes not only the meaning of the number of occurrences in the document but also the meaning of the proportion of words in the document.
[0009]
In the document processing apparatus described above, the evaluation phrase detection unit detects the evaluation phrase stored in the phrase storage unit from the document to be evaluated, and the evaluation phrase information creation unit detects the evaluation phrase detected by the evaluation phrase detection unit, or Then, evaluation information relating to an evaluation phrase composed of at least one of the appearance degrees of evaluation phrases is created, and evaluation information relating to the evaluation phrase created by the evaluation phrase information output means is output.
[0010]
Therefore, it is possible to obtain evaluation information related to the evaluation word / phrase from the document, and it is possible to evaluate whether the document is easy to understand for the user.
As described above, the user's understanding of the document can be evaluated from the evaluation information about the evaluation phrase between the understanding phrase in the document and the user's understanding of the contents of the document, and the ununderstood phrase in the document. This is because there is a relationship between the user and the difficulty of understanding the contents of the user's document.
The degree of understanding words in the document and the user's degree of understanding of the document content have a positive correlation, and the degree of understanding of the ununderstood words in the document and the degree of understanding of the document content have a negative correlation. is there.
That is, it can be evaluated that the higher the degree of appearance of the understanding phrase, the easier it is for the user to understand the content of the document, and the higher the appearance degree of the ununderstood phrase, the harder it is for the user to understand the content of the document. This is clear from the fact that the more words that can be understood in an English document, the easier it is to understand the content of the document.
[0011]
A document processing apparatus according to the present invention is a document processing apparatus that outputs evaluation information for performing understanding evaluation of a user's document based on a word / phrase in the document, and an understanding word / phrase understood by the user, or , A phrase storage unit that stores at least one of ununderstood phrases that the user does not understand as an evaluation phrase, an unknown phrase detection unit that detects an unknown phrase other than the evaluation phrase from the evaluation target document, and an unknown phrase An unknown phrase information creating means for creating evaluation information related to an unknown word composed of at least one of the unknown words detected by the detecting means and / or the degree of appearance of the unknown phrases, and an unknown that outputs evaluation information related to the created unknown words Phrase information output means.
[0012]
In the document processing apparatus described above, the unknown phrase detection unit detects an unknown phrase other than the evaluation phrase stored in the phrase storage unit from the document to be evaluated, and the unknown phrase information creation unit is detected by the unknown phrase detection unit. Evaluation information about an unknown word / phrase consisting of at least one of an unknown word / phrase and the degree of appearance of the unknown word / phrase is created, and the evaluation information about the unknown word / phrase created by the unknown word / phrase information output means is output.
[0013]
Therefore, it is possible to obtain evaluation information related to unknown words / phrases from the document, and to perform an understanding evaluation such as whether or not the document includes new contents for the user.
In this way, the user's understanding of the document can be evaluated from the evaluation information regarding the unknown word / phrase because the unknown word / phrase in the document is a word / phrase that the user has not previously treated as the evaluation word / phrase, and thus is completely new to the user. This is because a document containing the unknown word / phrase may contain new contents for the user.
Then, it can be said that the higher the appearance degree of the unknown word / phrase in the document, the higher the possibility that the content of the document contains new content for the user.
Here, it is preferable to use an understood word and an ununderstood word as an evaluation word. In this case, it is highly likely that the unknown word is a new word for the user, and therefore, the document including the unknown word is included. Is likely to contain new content for the user.
[0014]
In addition, the document processing apparatus according to the present invention further displays a document and accepts a phrase understanding reception that accepts designation input of at least one of an understanding word or an ununderstood word from a user for a word or phrase in the displayed document. And an evaluation phrase reflecting means for reflecting the phrase in the document to the phrase storage means based on the designation for the accepted phrase.
[0015]
In the document processing apparatus described above, the phrase understanding receiving unit displays the document, receives a specified input of at least one of an understanding phrase or an ununderstood phrase from the user for the phrase in the displayed document, and evaluates the phrase Based on the specification for the phrase received by the reflecting means, the phrase in the document is reflected in the phrase storing means.
Therefore, the user's understanding of the phrase can be appropriately reflected in the evaluation phrase in the phrase storage means.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
A document processing apparatus according to an embodiment of the present invention will be described with reference to FIG.
This document processing apparatus includes a document storage unit 1, an ununderstood word storage unit 2, an understanding word storage unit 3, an instruction input unit 4, a document evaluation unit 5, a document evaluation output unit 6, and a registration information change unit. 7.
[0017]
The document storage unit 1 is configured as a database, for example, and stores a plurality of documents to be evaluated.
The ununderstood word storage unit 2 stores ununderstood words that the user does not understand, and these ununderstood words are prepared as so-called dictionaries for each user.
The understanding word storage unit 3 stores the understanding words that the user has determined to understand, and these understanding words are prepared as so-called dictionaries for each user.
In the present embodiment, the understanding words and the ununderstood words are intended for independent words such as nouns, verbs, adjectives and adjective verbs.
[0018]
The instruction input unit 4 includes an input device such as a keyboard and a mouse. An input for specifying a document to be evaluated from a user, a request input for displaying a document, and designation of an ununderstood word for a word in the document Accept input.
The document evaluation unit 5 acquires the document specified by the instruction input unit 4 from the document storage unit 1 and uses the understanding words and the ununderstood words stored in the ununderstood word storage unit 2 and the understanding word storage unit 3. And processing for creating evaluation information for the acquired document.
The document evaluation output unit 6 outputs document evaluation information created by the document evaluation unit 5 to an output device (not shown) such as a display.
[0019]
The registration information changing unit 7 displays the document stored in the document storage unit 1 on the output device, receives a designation input for an ununderstood word in the document from the instruction input unit 4, and based on the designation, A process of reflecting the words as ununderstood words and understood words in the ununderstood word storage unit 2 and the understood word storage unit 3 is performed.
[0020]
Here, the phrase storage means referred to in the claims is constituted by the ununderstood word storage section 2 and the understanding word storage section 3, and the evaluation phrase detection means and unknown phrase detection means referred to in the claims are: The evaluation information output means and the unknown phrase information creation means, which are configured by the evaluation section 5 and are referred to in the claims, are configured by the document evaluation output section 6, and the phrase understanding reception means in the claims are the instruction input section 4. And the registration information changing unit 7 work together, and the evaluation phrase reflecting means referred to in the claims is constituted by the registration information changing unit 7.
[0021]
Next, the operation of the above document processing apparatus will be described.
The processing of this document processing apparatus can be broadly divided into an evaluation information output process for creating and displaying evaluation information for a document stored in the document storage unit 1, and a phrase in the document as an unrecognized word and an ununderstood word. There is a registration change process to be reflected in the understanding word storage unit 2 and the understanding word storage unit 3.
[0022]
First, the operation in the evaluation information output process of the document processing apparatus will be described with reference to FIG.
The instruction input unit 4 receives an input for specifying a document to be evaluated by the user, and the document evaluation unit 5 reads the document to be evaluated specified by the input from the document storage unit 1 into its own memory (not shown) and reads it. The document is decomposed into words for each part of speech and stored in its own memory (steps S1 and S2). FIG. 4A shows a result obtained by decomposing the document shown in FIG. 3 into words for each part of speech. In this embodiment, individual words are stored in a form separated by commas.
[0023]
Next, the document evaluation unit 5 performs the following classification process (steps S3 to S9) for each of the words decomposed into parts of speech.
In this classification process, first, it is determined whether or not the word decomposed into parts of speech is an independent word (steps S3 and S4).
If the word is not an independent word, classification processing is performed on another word that has been decomposed into parts of speech.
On the other hand, if it is an independent word, it is determined whether or not the word is stored as an ununderstood word in the ununderstood word storage unit 2 (step S5), and further stored in the understanding word storage unit 3 as an understanding word. It is determined whether or not it has been performed (step S6).
[0024]
As a result, if the word is stored as an ununderstood word, it means that the user does not understand the word, so the word is registered in the ununderstood word storage area in its own memory ( If it is stored as an understanding word in step S7), it means that the user understands the word, so that the word is registered in the understanding word storage area in its own memory (step S7). S8) If it is not stored in any of them, it means that the word is not grasped by the user as an understood word and an ununderstood word, so that the word is stored in an unknown word in its own memory. Registration in the area (step S9). Note that after completing registration in any storage area, the above-described classification processing is performed for other words.
When the above-described classification processing is performed on each word shown in FIG. 4A, for example, the ununderstood word storage area is as shown in FIG. 4B, and the understood word storage area is shown in FIG. 4C. Thus, the unknown word storage area is as shown in FIG.
[0025]
When the above classification process is performed for all words that have been decomposed into parts of speech, the document evaluation unit 5 counts the number of understood words, ununderstood words, and unknown words stored in its own memory. Furthermore, the number of understood words, ununderstood words, unknown words is totaled, and evaluation information is created by calculating the ratio of each of the understood words, ununderstood words, unknown words, and the created evaluation information is a document evaluation output unit. 6 (steps S3 and S10).
Then, the document evaluation output unit 6 that has received the evaluation information outputs the evaluation information to the output device (step S11). FIG. 5 shows an example of evaluation information for the document shown in FIG.
Therefore, based on the evaluation information, the user can easily determine whether or not the document is difficult for the user and whether or not the document includes new contents without reading the document.
[0026]
Next, the registration change processing operation of the document processing apparatus will be described with reference to FIG. In the present embodiment, the change registration process is performed when there is a display request for a document whose notation information is output by the above-described evaluation information display process.
When there is a display request for the document, the registration information changing unit 7 displays the corresponding document on the output device, and the instruction input unit 4 inputs a mark (designated input) with an ununderstood word from the user for the word in the document. The registered information changing unit 7 receives and marks the marked word input by the instruction input means 4 temporarily in its own memory (step S21).
After the mark input by the user is completed, the registration information changing unit 7 performs the following processing (steps S22 to S26) for each stored word.
[0027]
First, it is determined whether or not the stored word is an ununderstood word (step S23).
The determination as to whether or not the word is an ununderstood word is quickly made based on whether or not the word is included in the ununderstood word storage area in the document evaluation unit 5 created in the above-described evaluation information output process. Can do. The determination can also be made based on whether or not the ununderstood word storage unit 2 stores it.
[0028]
As a result of this determination, if the word is an ununderstood word, it means that the word has already been registered in the ununderstood word storage unit 2 as an ununderstood word, so processing for other words without doing anything I do.
On the other hand, if it is not an ununderstood word, it is determined whether or not it is an understood word (step S24).
Whether or not the word is an understanding word can be quickly determined based on whether or not the word is included in the understanding word storage area in the document evaluation unit 5 created in the above-described evaluation information output process. . The determination can also be made based on whether or not it is stored in the understanding word storage unit 3.
[0029]
As a result, if it is not an understanding word, it means that it is stored in the unknown word storage area in the document evaluation unit 5 as an unknown word in the above-described evaluation information output process, so it is deleted from the unknown word storage area At the same time, the word is stored in the ununderstood word storage unit 2 as an ununderstood word, and processing for other words is performed (step S25).
On the other hand, in the case of an understanding word, it means that the user previously understood the word but is not currently understood. While deleting, it stores as an ununderstood word in the ununderstood word storage part 2, and processes about another word (step S26).
[0030]
If the above processing is completed for all words stored in the memory of the registration information changing unit 7, it means that the unknown words remaining in the unknown word storage area of the document evaluation unit 5 are understood words. Therefore, the unknown word stored in the unknown word storage area is stored in the understanding word storage unit 3 as an understanding word (steps S22 and S27).
[0031]
In the above registration change process, when the user actually reads the document shown in FIG. 3, only the word “antihistamine” cannot be understood and only the word “antihistamine” is marked as an ununderstood word. In the case of the input, “antihistamine” is registered as an ununderstood word in the ununderstood word storage unit 3 and is deleted from the unknown word storage area shown in FIG. . Since there is no word other than “Antihistamine” that has been entered as a mark, the “secretory gland” remaining in the unknown word storage area is registered as an understanding word in the understanding word storage unit 3.
[0032]
Thus, it can be easily and appropriately reflected as an ununderstood word and an understanding word based on whether or not the user understands a certain word.
Further, it is possible to prevent a word already registered in the ununderstood word storage unit 2 or the understanding word storage unit 3 from being registered as an ununderstood word or as an understand word.
[0033]
In the embodiment described above, unknown words, ununderstood words, the number of understood words, etc. in the document are output as evaluation information. However, unknown words, ununderstood words, and understood words themselves are output. However, it can be used for understanding evaluation of documents.
In the above-described embodiment, ununderstood words and understood words are used as evaluation phrases, but evaluation information for understanding and evaluating a document can be obtained using only one of them.
[0034]
In the above-described embodiment, the evaluation information for the document instructed by the user is output. For example, information for specifying a plurality of documents selected from a search device that performs a search such as a keyword search is used. Upon receipt, the evaluation information for these documents may be output .
[0035]
In the above-described embodiment, the evaluation information is output to an output device such as a display. However, the evaluation information may be output to a storage device such as an electronic file or a database.
When the evaluation information is output to a storage device such as an electronic file in this way, for example, based on the evaluation information, a predetermined standard (for example, the percentage of comprehension words exceeds 80% based on the user's request, etc.) If a device having a function of selecting a document satisfying (2) is input, it is possible to select a document suitable for the user without the user's own judgment.
[0036]
Each functional unit described above is configured by a processor executing a control program (stored in advance in ROM, RAM, etc.). However, in the present invention, these functional units may be configured as independent hardware circuits. Good.
In addition, the present invention allows the above control program to be grasped as a computer-readable storage medium such as a floppy disk or a CD-ROM, and the control program is read from the storage medium and executed by a processor. Such processing can also be executed.
[0037]
【The invention's effect】
As described above, in the document processing apparatus and method according to the present invention, at least one of an understanding word that the user understands or an ununderstood word that the user does not understand is stored as an evaluation word. Since the evaluation phrase is detected from the document to be evaluated and the evaluation information including at least one of the detected evaluation phrase and the appearance degree of the evaluation phrase is created and output, the output evaluation is performed. Based on the information, it is possible to evaluate whether the document is easy to understand for the user.
[0038]
Further, in the document processing apparatus and method according to the present invention, at least one of an understanding word that the user understands or an ununderstood word that the user does not understand is stored as an evaluation word, and the evaluation target An evaluation that is output because an unknown word / phrase other than the evaluation word / phrase is detected from the document, and evaluation information including at least one of the detected unknown word / phrase and / or the appearance degree of the unknown word / phrase is created and output. Based on the information, it is possible to perform an evaluation of whether or not the document includes new contents for the user.
