Description

  The present invention relates to a topic presentation method and apparatus and system, a program, and a storage medium storing the program, and more particularly, a topic presentation method and apparatus and system for providing a topic in a communication system such as a presentation version system and a chat system. The present invention also relates to a program and a storage medium storing the program.

  In a network communication place (channel) using a bulletin board system or chat system, useful information such as reputation, problem solving, new viewpoints, and incidents in the community is generated. In addition, users with the same interest gather and have a conversation, so the conversation is exciting and you can enjoy the conversation just by looking at the conversation. Users can get useful information and enjoy conversations there by checking what topics are exciting in the channels they use every day.

  However, the place of communication using a bulletin board system and a chat system has increased with the spread of the Internet in recent years. As a result, the number of channels used by users is increasing, and it takes a lot of time to check what topics are popular in the channels that they participate in every day.

  Also, for users who know the place for the first time, if they do not actually participate (peek) and do not know what is being spoken there, the threshold for participation in that place is high, and it is difficult to incorporate new users. For this reason, it is desired that the user can understand at a glance what topics have recently attracted interest on the channel.

  As a technique for presenting topics spoken in bulletin board systems and chat systems, for each channel, there is a method of extracting a word sequence that matches the part-of-speech pattern prepared from the messages in the channel as a topic. is there. For example, the pattern to be prepared is a pattern that attracts the user's interest, such as a string of nouns or a character string in which nouns are connected by “no”. Then, for each channel, a high score is given to the topic extracted from the channel, and the higher the score that is newer in the channel and near the latest message of the channel, the higher score is selected. To do.

This method selects a topic that is new and more densely generated in the vicinity of the latest message from the extracted topics in order, so that it can follow changes in the topic as the conversation progresses. Easy to grasp movement. Moreover, since a character string composed of a plurality of words becomes a topic and a specific topic is presented, it is easy for the user to determine whether the presented topic is a known topic ( For example, see Patent Document 1).
JP 2004-348415 A

  In the above conventional technique, a topic score is obtained for each channel based on the latest message of the channel. Therefore, even if the score is high, it is not necessarily the topic that has been recently spoken when viewed by the user. As a result, when the user thinks that the topic is a recent topic when he / she sees it, he / she goes to the place of conversation and is actually an old topic.

  As a coping method, for example, the posting time of the final message can be presented. Thereby, when the posting time of the final message is old, the user can grasp that there is only an old topic.

  However, with this method, it is not possible to deal with the posting of a message that does not have a content that cannot be used even when the update time is recent.

  In addition, by presenting topic words as subject words extraction targets only for messages within a specified period of time when the message was posted by the user (time when the system presented the topic word to the user), There may be a method of preventing old topic words outside the specified range from being presented.

  However, if there is no topic word within the specified period, the topic word is not presented. As a result, the user cannot understand what kind of conversation can be made on the channel, and thus is not interested, resulting in an obstacle to the user's visit to the channel.

  The present invention has been made in view of the above points, and grasps the topic that the user's interest is gathering at the end of the conversation in the channel and whether it is a recent topic at the time the user sees it. It is an object of the present invention to provide a topic presentation method, apparatus, system, program, and storage medium storing the program that can be grasped simultaneously.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 3 shows a configuration of the topic presentation device according to the first embodiment of the present invention.

  A topic presentation device 100 shown in the figure is connected to an input device 10 such as a keyboard and a mouse and a display device 20 which is a display.

  The topic presentation device 100 includes a counter value storage unit 102, a morphological analysis unit 103, a pattern storage unit 104, an analyzed message storage unit 105, an appearance message number storage unit 106, a word appearance latest time storage unit 107, and a topic constituent word storage unit 108. , A presentation topic word creation unit 109, a topic list storage unit 110, a channel information table creation unit 111, a time range storage unit 112, a display topic number storage unit 113, and an out-of-period topic display format storage unit 114.

  The counter value storage unit 102 stores an integer value that is updated each time the message is registered and indicates the number of registered messages in order to grasp the registration order of the messages. The initial value of the counter value storage unit 102 is 0.

  The morphological analysis unit 103 divides the character string into words for the character string input from the input device 10 and outputs the words and the part-of-speech information. This apparatus is a generally used apparatus. For example, a tea bowl system provided by Nara Institute of Science and Technology can be used as the morphological analysis unit 103.

  The pattern storage unit 104 stores the definition of the character string pattern extracted from the character string data. For example, a regular expression “(noun (no)?) + Noun” using a part of speech is stored. The pattern represents a character string in which a series of nouns or “no” between nouns is connected.

  The analyzed message storage unit 105 corresponds to the topic group in the message that matches the pattern stored in the pattern storage unit 104 for the message input to the topic presentation device 100, and each topic of the topic group. And the channel identifier given at the time of the registration request of the message, the time, and the counter number given to the character string data are stored in association with each other. FIG. 4 shows an example of an input message, and FIG. 5 shows an example of data stored.

  The number-of-appearing message storage unit 106 stores the number of messages of each channel in which the word appears for each word in the message group in the message group. FIG. 6 shows an example of data stored in the appearance message storage unit.

  The word appearance latest time storage unit 107 stores, for each word of each channel, the time associated with the latest message in the message in which the word appears in the channel. FIG. 7 shows an example of data stored in the word appearance latest time storage unit. In the present embodiment, for convenience, the time is expressed in epoch seconds. Epoch seconds represent the number of seconds since midnight on January 1, 1970 in GMT (World Standard Time).

  The topic constituent word storage unit 108 stores, for each topic of each channel described above, the words constituting the topic. FIG. 8 shows an example of data recorded in the topic constituent word storage unit 107.

  The presentation topic word creation unit 109 creates a topic to be presented from sequentially registered messages.

  The presentation topic word creation unit 109 stores a registration request list input from the input device 10 in a memory (not shown), acquires a channel identifier, a message, and a time from the registration request list, and is input to the channel identifier. A character string group that matches the part-of-speech pattern in the pattern storage unit 104 is obtained as a topic group from the message group. The number of messages in which the word constituting the topic appears in the message of the channel identifier input after the message in which the topic extracted for each topic of each message appears is obtained as the support number. Number of messages entered later with a numerator component weighted by an expression with the denominator as the number of messages in which the word appears in the message entered for the channel identifier for which the support number was entered Are related to the input channel identifier and output to the topic list storage unit 110 by an expression having as a component of the denominator.

  Further, for each extracted topic, the topic word and the word constituting the topic are associated and output to the topic constituent word storage unit 108. For each word of the input message, the word value of the input channel identifier in the word appearance latest time storage unit 107 is updated at the given time as an input. For example, “1047886510 (2003/03 / 17-10: 45: 10)” is related to the time of the input message “Hanako's costume is yellow jumpsuit”, and the message in the word appearance latest time storage unit 107 is related. When the latest appearance time of the word “Hanako” for the same channel identifier is “1047864615 (2003/03/17/10: 30: 30: 15)”, the word “Hanako” of the channel in the word appearance latest time storage unit 107 The value is updated to “10478655510”. FIG. 7 shows an example of the word appearance latest time storage unit 107 updated as described above. FIG. 9 shows an example of data stored in the topic list storage unit 110.

  The detailed operation of the presentation topic word creation unit 109 will be described later.

  The time range storage unit 112 stores a time length for defining at least how much time has elapsed since the message was generated as a topic that has not been recently spoken. For example, in order to distinguish topics that are not spoken within 5 minutes, for example, “300” in units of seconds is stored.

  The display topic number storage unit 113 stores an integer that defines the maximum number of topics to be presented to the user in each channel. For example, “3” is stored when three topics are presented for each channel.

  The non-period topic display format storage unit 114 stores a display command for distinguishing topics that have not been recently spoken from others. For example, when displaying in the HTML format, it is possible to use a tag for designating the font size and color. FIG. 10 shows an example of the off-period topic display format storage unit 114. “WADAI_P” in the figure is replaced with w (topic) in step 216 of FIG. 13 described later. The example in FIG. 10 represents an instruction to display a font in gray that is three levels smaller than the others.

  The channel information table creation unit 111 creates and displays a table that lists channels and their topics, which expresses the topics created by the presentation topic word creation unit 109 in a format that can be distinguished from topics that have not been spoken recently. Detailed operation will be described later.

  11 and 12 are flowcharts of the operation of the presented topic word creation unit in the first embodiment of the present invention.

  Step 101) The presented topic word creation unit 109 terminates the following process when an end instruction is given.

  Step 102) It is determined whether the registration request list in the memory (not shown) is empty, and if it is empty, the process returns to Step 101.

  Step 103) Acquire the registration request list and read out the first channel identifier, message, and time pair of the registration request list. The channel identifier of the read set is ID, the message is d, and the time is A. The read set is deleted from the registration request list in the memory (not shown).

  Step 104) The counter value is read from the counter storage unit 102, 1 is added, and C is obtained (C = C + 1). If there is no corresponding counter, C = 1. The counter value C is stored in the counter storage unit 102.

  Step 105) The message (d) is output to the morphological analysis unit 103, and the list L = [[S1, T1], [S2, T2],...] Having the pair [Si, Ti] of the word Si and the part of speech Ti as elements. (S1, S2) are acquired in order from the first word of the message (d).

  Step 106) The pattern is read from the pattern storage unit 104, and this is set as P.

Step 107) A list R for storing a topic in a message and a set of words constituting the topic, a list U for storing a word constituting each topic, a character string S for storing a suggested topic candidate, A character string T for storing a part-of-speech character string and a list W for storing words in a message are prepared in a memory (not shown).
R = [], U = [], S = """", T = """", W = []
And

  Step 108) i = 1.

  Step 109) If i ≦ L, the process proceeds to Step 120. Otherwise, the process proceeds to Step 110.

  Step 110) In a memory (not shown), a character string for storing a part-of-speech character string is set to T = T + Ti.

  Step 111) If there is a portion in T determined in step 110 that does not match the pattern P acquired in step 106, the process proceeds to step 112. If there is a match, the process proceeds to step 115.

  Step 112) It is determined whether S = “” “”. If so, the process proceeds to Step 113, and if not, the process proceeds to Step 114.

  Step 113) Set T = “” “” and go to Step 116.

  Step 114) U (word) is output as the value of S (topic) of the ID (channel identifier) in the topic constituent word storage unit 108, and the process proceeds to step 116.

R = R + [[S, U]]
S = """", T = """", U = []
Step 115) In a memory (not shown), a character string S for storing the presentation topic candidates, a list U for storing words constituting each topic, and a character string T for storing part-of-speech character strings, respectively. ,
S = S + Si
U = [Si] + U
T = T + Ti
And

  Step 116) If SiεW, go to Step 119, otherwise go to Step 117.

  Step 117) A list W for storing words in the message is W = W + [Si].

  Step 118) The Si value (number of appearing messages) of the ID (channel identifier) is read from the appearing message number storage unit 106, and a value obtained by adding 1 to the value is output to the Si value of the ID of the appearing message number storage unit 106. . When there is no corresponding value in the appearance message number storage unit 106, 1 is output. A (time) is output as the value of Si of the ID (channel identifier) in the word appearance latest time storage unit 107.

  Step 119) Set i = i + 1 and proceed to Step 109.

  Step 120) R (list for storing a topic in a message and a set of words constituting the topic), ID (channel identifier), C (counter value), W (list for storing a word in the message) A list having W) as an element is created and stored in the analyzed message storage unit 105 as an analyzed message.

  Step 121) The analyzed message group G including the ID as an element is read from the analyzed message storage unit 105, and the number of appearing messages of each word related to the ID is read from the appearing message number storage unit 106.

  Step 122) A list M = [] for storing topics and their scores is prepared on a memory (not shown).

  Step 123) For each topic Zij in each analyzed message i of the message group G, the support number SUPPORTk of each word k constituting the topic Zij (the counter value larger than that message in the message group in G The number of messages having the word k) and the number of messages RESTi in G having a counter value larger than that message, and the number of words constituting the topic Zij as Nij,

をスコアとして算出する。

Is calculated as a score.

  Step 124) Each topic ij is paired with the score ij and added as an element of M. At this time, if there is already a pair in M that has the same topic as the topic ij as an element, the topic ij in M only if the score v of the topic ij in M is smaller than the score ij. The pair having the topic ij and the score ij are paired and added to M.

  Step 125) When the list for the ID exists in the topic list storage unit 110, the list for the ID is deleted from the topic list storage unit 110. The pairs in M are sorted in descending order of the score value, the sorting result list and ID are paired and stored in the topic list storage unit 110, and the process returns to step 101.

  In step 123 described above, a value using the number of support according to the occurrence density of the topic between each message and the latest message is obtained, and in step 124, the maximum value using the number of support in each topic is determined. By adopting it as a score value, the score of a topic where users gather at the end of the conversation tends to increase. As a result, in the present invention, the topic presented to the user tends to be a topic that attracts the user's interest at the end of the conversation, and the topic that attracts the user's interest at the end of the conversation in the channel Can be grasped.

  Next, the operation of the channel information table creation unit 111 will be described in detail.

  FIG. 13 is a flowchart of the process of the channel information table creation unit in the first embodiment of the present invention.

  Step 201) The channel information table creation unit 111 stores L in the data stored in the topic list storage unit 110, W stores the data stored in the topic constituent word storage unit 108, and stores the data in the latest word appearance time storage unit 107. Data stored in the display topic number storage unit 113, N data stored in the time range storage unit 112, Tterm, and data stored in the out-of-period topic display format storage unit 114. Read as F.

  Step 202) Let Lc = a list having each channel identifier on L as an element.

  Step 203) If an end instruction is input, the process ends.

  Step 204) Tcurrent = current time, and list R = [] for storing a pair of a channel identifier and a list of topics to be presented. Let C = Lc.

  Step 205) It is determined whether C on the memory (not shown) is an empty list. If it is an empty list, the process proceeds to Step 209. If not, the process proceeds to Step 206.

  Step 206) A list with the channel identifier c ′ = C as the first element, a list obtained by removing the first element from C = C, and elements (topics) on L with L ′ = c ′ are arranged from the top in the descending order of score values. A list L ″ = [] for storing a list of channel topics on the table is set in a memory (not shown).

  Step 207) It is determined whether L 'is an empty list. If it is an empty list, the process proceeds to Step 208. If not, the process proceeds to Step 210.

  Step 208) The list R is set to R = R + [[c ′, L ″]], and the process proceeds to Step 205.

  Step 209) A display table is created in which the list R is a channel identifier as an item, and a character string in which elements of the topic list of the channel identifier in the list R are separated for each element is used as the value of the corresponding channel identifier item. Then, the data is output to the display device 20, and the process proceeds to step 203.

  Step 210) It is assumed that the topic of the top element of w ′ = L ′, a list obtained by removing the top element from L ′ = L ′, and a list having the words constituting C ′ of Lk = W as elements.

  Step 211) It is determined whether Lk is an empty list. If it is an empty list, the process proceeds to Step 207. If not, the process proceeds to Step 212.

  Step 212) It is assumed that k = Lk is the top element, and Lk = Lk is a list obtained by removing the top element.

  Step 213) If Tcurrent− (value of k ′ of S ′) ≦ Tterm, the process proceeds to Step 214; otherwise, the process proceeds to Step 215. Here, when there is no k value of c ′ of S, the value of k of S ′ is calculated as 0.

  Step 214) L ″ = L ″ + [w ′] and Lk = [], and the process proceeds to Step 211.

  Step 215) It is determined whether Lk is an empty list. If it is an empty list, the process proceeds to Step 216. If not, the process proceeds to Step 211.

  Step 216) A character string m in which w ′ is embedded in a predetermined place of the data F is created, L ″ = L ″ + [m], and the process proceeds to Step 211.
