Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a message generation device in natural language that can be applied to a public database search device and other harmful species information processing devices (systems).

[Theft] U1 Yu In recent years, in various information processing systems, methods have been increasingly used in which the operator processes the system and the entire language in natural language, but in such cases, messages from the system generally have one meaning. The content was displayed in one fixed sentence.

In other words, the message generator used in conventional information processing systems stores in advance data for one message for each content that the system is expected to need to convey to the operator, and Messages could be selected and displayed as needed.

However, in natural language conversation systems, the richness of conversation sentences is important, and the conventional message generators described above are not sufficient, especially for database search systems.

Therefore, if you try to create multiple messages with the same meaning and variation using the conventional method, the number of messages to be memorized will increase several times, and the storage capacity will become extremely large. Fortunately, the cost increased significantly because memory was required.

Purpose This invention was made in view of the above points, and an object of the present invention is to make it possible to generate a wide variety of message sentences for the same meaning without significantly increasing the storage capacity of the memory. do.

l-wei In order to achieve the above object, the first invention is as follows.

a first dictionary memory storing a message dictionary in which the type of message is used as a key and decomposition of independent words and attached words is specified in accordance with the order of clauses of a sentence as one item;

a second dictionary memory storing a word dictionary in which independent words and attached words are grouped according to the field;

A message search device for obtaining message information by searching a message dictionary in the first dictionary memory according to the type of message.

Search the word dictionary in the second dictionary memory according to the independent word and dependent word fields of message information from the device, select one of the independent words or dependent words for each grouped field, and write the message. The present invention provides a message generation device comprising a sentence generation device and a sentence generation device.

Furthermore, the second invention includes: a first dictionary memory storing a message dictionary in which the type of message is used as a key and fields of independent words and attached words are specified according to the clause order of the sentence as items;

A second dictionary stores a word dictionary in which independent words and attached words are grouped according to the above-mentioned fields, and information on connecting symbols is added.
with dictionary memory.

a connectability information memory that stores information on connectability for the combination of connection symbols; a message search device that retrieves message information by searching the message dictionary of the first dictionary memory according to the type of message; and from the device. The phrase information in the message information is selected using random numbers, and the word dictionary in the second dictionary memory is searched according to the independent words and attached word fields of the selected phrase, and the independent words are searched for each grouped field. or a message generating device that selects one of the attached words and generates a message by checking whether or not the connection is possible based on the information in the connection possibility information memory using the connection symbol added thereto. This is what we provide.

Note that in this specification, the term "field" refers to a collective term for synonyms of words.

Hereinafter, each of these inventions will be specifically explained based on implementation.

FIG. 1 is a block diagram showing the configuration of an embodiment of the first invention, which includes a first dictionary memory 1 storing a message dictionary, a second dictionary memory 2 storing a word dictionary, and a message retrieval device. 32 sentence generator 4. The control bag aS and the input/output device 6 consisting of a keyboard and a CRT display constitute a message generating device.

In the message dictionary stored in the first dictionary memory 1, the types of messages are used as keys, and fields of independent words and attached words are specified in reverse order of the clauses of sentences as items.

In the word dictionary stored in the second dictionary memory 2, independent words and attached words are grouped by field.

Message search bag! [3] searches the message dictionary in the first dictionary memory 1 according to the type of message specified by the control device 5, obtains message information, and sends the message information to the sentence generation device 4.

The sentence generation device 4 searches the word dictionary in the second dictionary memory according to the fields of independent words and attached words in the message information from the message retrieval device 3, and searches the word dictionary of the second dictionary memory for independent words or attached words for each grouped field. Select to generate a message and send it to the control bag riis.

When the message type M is specified in the system, the control device 5 receives it, sends it to the message search bag [3], sends the message generated by the sentence generation device to the input/output device 6, and sends it to the CRT. It is displayed on the display 6a.

Note that even if the control device 5 and the input/output device 6 of this embodiment are omitted, it is still possible to generate a message according to the specified message type, so that the message generation device according to the present invention can still be used.

Next, the operation of this embodiment will be explained using an example in which this embodiment is applied to a database search system.

Let MO be the type of message when the database is searched but nothing is found.

An example of message dictionary entries for this message type M is shown in FIG.

The message M shown in Fig. 2 consists of three clauses,
The first clause P, consists of independent word item J4, and the second clause P2
consists of an independent word item J8 and an adjunct word item 'F3, and the third clause P3 consists of an independent word item J +o. Note that "-" in FIG. 2 indicates "no item".

The contents of the word dictionary for each of these independent words (words that have meaning on their own) and adjunct words (words that have no meaning on their own, such as particles), that is, examples of word groups grouped by field, are shown in Section 6. Shown in Figures (a) to (d).

Therefore, first, when the message seed 111 Mo is sent to the control device 5, it is transmitted to the message search device 3, which searches the message dictionary in the first dictionary memory 1 and retrieves the message seed 111Mo. The message information shown in FIG. 2 is obtained and sent to the sentence generation device 4.

The sentence generation device 4 searches the word dictionary (FIG. 3) in the second dictionary memory 2 in order from the first clause item, except for the MO indicating the type of message from this message information, and searches the word dictionary (Fig. Select any one of the words in the field using random numbers.

Replace the items in the message information in Figure 2.

For example, first, the word dictionary is looked up at J4 in FIG. 2, and the three words shown in FIG. 3 (,) are obtained. Generate a random number here and
If ``1'' appears, select ``Applicable'', if ``2J'' appears, select ``J entered, and if ``3'' appears, select ``desired''.

Now, if the random number is ``2'', select ``Input'' and enter ``Input'' in place of item J4 in the message information of FIG. 4, as shown in FIG.

Thereafter, the same process is performed for the item JayF3J+o. When the processing up to JIO is completed, the message information becomes as shown in FIG. 5, for example.

The sentence generation device 4 sequentially extracts the character strings of the sentences generated in this way and sends them to the control device 5, and sends them to the CR of the input/output device 6.
The T-display 6a displays ``There is no input item.''

Also, depending on random numbers, the following message may be displayed instead of this message.

[No matching information found] "The desired content was not found" and many more In this way, a certain type of message has one basic form, but a message text can be generated using random numbers in many different expressions with the same meaning. Since you can do this, your conversation sentences will be richer.

Next, another embodiment in which the above embodiment is partially modified will be described.

The block configuration of this embodiment is the same as that shown in FIG. 1, but the functions of the sentence generation device 4 and the contents of the word dictionary stored in the second dictionary memory 2 are slightly different.

That is, when searching each item of the word dictionary and selecting words (independent words or attached words) for each field, the sentence generation device 4 of this embodiment sequentially searches for candidate words without using random numbers. Then, select the first word for which O" is set in the selection checkbox of the word dictionary. Then, set 1" in the selection checkbox of the selected word in the word dictionary.

At the time of word selection, if 1'' is set for all candidate words, all selection/non-selection sieves in the word dictionary are reset to 0'' and the first word is selected.

Therefore, in the word dictionary of the second dictionary memory 2.

As shown in Fig. 6, a selection tone is provided for each word in each field, and the following 1'' or 0'' is added to it as data indicating whether or not it has been selected by the sentence generation device 4. ing.

1: Previously selected 0: Not yet selected This embodiment is further modified so that when the sentence generator 4 selects a word, it does not sequentially search for candidate words, as described first. Random numbers may be used as in the embodiment described above.

In this case as well, information on whether or not the word is selected is added to the word dictionary.
Allows you to choose from words that are not already selected.

These embodiments also allow messages with the same meaning to be expressed in a wide variety of sentences.

Moreover, it is not necessary to increase the storage capacity of the memory so much.

Next, the configuration of the second embodiment of the invention will be explained with reference to FIG.

This embodiment is also constructed in substantially the same manner as the embodiment shown in FIG. 1, and the same parts are given the same reference numerals. The contents of the word dictionary in the dictionary memory 12 and the functions of the sentence generating device 14 are somewhat similar to the contents of the word dictionary in the second dictionary memory 2 and the functions of the sentence generating device 4 shown in FIG.

The word dictionary in the second dictionary memory 12 has added information on a connecting symbol (in this example, "3" for the independent word item JIo) as shown in FIG.

In addition, in the connection availability information memory 10, the connection symbols of the two clauses before and after 1 are stored in the row number (later clause) and column number (previous clause).
In the connection check table based on the matrix, the information on whether or not the connection is possible is expressed as 1'' (connection possible) and "o" (connection not possible), and for the connection symbol in the line, there are The information is shown as 1" (acceptable) and 0" (unacceptable), respectively.

Then, the one-sentence generation device 14 generates phrase information (
Random numbers are used to select independent word items).

Accordingly, the selected phrase information is stored in the second dictionary memory 1.
2. Search the word dictionary of 2 and select one word from the candidates of the item +1 using random numbers or sequential search, and look at the connecting symbol added to the item.

Based on the connection symbol, the connection check table in the connection information memory 10 is used to check whether or not it can be connected to the previous clause, and if it is a clause at the beginning or end of a sentence, it is also checked, and if either is not, the clause is connected. Cancel the selection and select again using random numbers.

For example, if a random number is generated for the message information shown in Figure 2 and "3" is output, rJlO-
When the third clause of J is selected and the word dictionary is searched using its independent word item J +o, there are three words with "3" added as a connecting symbol, as shown in FIG.

Then, a random number is generated again and one of the words is selected, but if ``1'' is returned, ``None'' is selected.

Furthermore, the line number of the connection check table shown in FIG. 9 stored in the connection availability information memory 10 is drawn using the connection symbol "3" for this word.

In this case, since it is the beginning of a sentence, we first look at the sentence-initiality information in the third line, and since it is 0'', we can say that this word cannot be connected, so we cancel the first selection and select a random number from among the remaining phrases. Perform the selection and connection check as described above.

Also, when you select a word in a clause other than the beginning of a sentence, subtract the line number in the connection check table using the connection symbol of the word in that clause,
The column number of the connection check table is subtracted from the connection symbol of the word of the clause selected immediately before, and the connection possibility is checked based on the connection possibility information of the intersection point.

In this way, a message sentence is generated by arbitrarily selecting the order of the clauses within the connectable range, and by arbitrarily selecting the words of each clause within the range available in the word dictionary.

Therefore, it is possible to obtain a greater variety of message texts than in each of the embodiments described above.

Effects As explained above, according to the first and second inventions, the same low-quality message text can be generated in various ways without significantly increasing the storage capacity of the memory. This allows for richer natural language conversations in various information processing systems.

According to the second invention, since the order of the clauses of the message sentence also changes, a conversation sentence rich in layer changes can be obtained.
