There is provided an information retrieval apparatus which can properly retrieve information associated with a user's preference from one of a plurality of data bases having different use frequencies. An information retrieval apparatus includes: a retrieval instruction issue unit which identifies one of an information source A data base, an information source B data base and an information source C data base according to the user's operation; a retrieval keyword selection unit which preferentially selects, from a group of keywords indicating the user's preference, one or more strongly preferred keywords based on a number associated with the use frequency of the data base identified by the retrieval instruction issue unit; and a retrieval unit which retrieves information including the one or more keywords selected by the retrieval keyword selection unit from the data base identified by the retrieval instruction issue unit.

There is provided an information retrieval apparatus which can properly retrieve information associated with a user's preference from one of a plurality of data bases having different use frequencies. An information retrieval apparatus (100) includes: a retrieval instruction issue unit (102) which identifies one of an information source A data base (101A), an information source B data base (101B) and an information source C data base (101C) according to the user's operation; a retrieval keyword selection unit (105a) which preferentially selects, from a group of keywords indicating the user's preference, one or more strongly preferred keywords as many as a number associated with the use frequency of the data base identified by the retrieval instruction issue unit (102); and a retrieval unit (106) which retrieves information including the one or more keywords selected by the retrieval keyword selection unit (105a) from the data base identified by the retrieval instruction issue unit (102).
摘要:
A speech recognition device presenting whether a user's utterance is an unregistered word and whether the utterance should be repeated. The device includes a vocabulary storage unit (102) defining a vocabulary for speech recognition, and a speech recognition unit (101) checking the uttered speech against registered words. The device also includes a similarity calculation unit (103) calculating a similarity between the uttered speech and acoustic units, a judgment unit (104) judging, based on the check by the speech recognition unit (101) and the calculation performed by the similarity calculation unit (103), whether the uttered speech is a registered or unregistered word, an unregistered word unit (106) storing unregistered words, an unregistered word candidate search unit (105) searching the unregistered word unit (106) for unregistered word candidates, the, when the judgment unit (104) judges that the uttered speech is an unregistered word, and a display unit (107) displaying the result.

A speech recognition device that is capable of presenting, to a user in an easy-to-understand manner, whether or not the user's utterance is a word unregistered in a speech recognition dictionary and whether or not the utterance should be repeated due to a recognition error includes: a speech recognition vocabulary storage unit (102) which defines vocabulary for speech recognition; a speech recognition unit (101) which checks the uttered speech against the registered words; a reference similarity calculation unit (103) which calculates a similarity between the uttered speech and a combination of acoustic units, which are subwords; an unregistered word judgment unit (104) which judges, based on the result of the check by the speech recognition unit (101) and a result of the calculation performed by the reference similarity calculation unit (103), whether the uttered speech is a registered word or an unregistered word; an unregistered word storage (106) which stores unregistered words; an unregistered word candidate search unit (105) which searches the unregistered word storage unit (106) for unregistered word candidates that are likely to correspond to the uttered speech, in the case where the unregistered word judgment unit (104) judges the uttered speech to be an unregistered word; and a result display unit (107) which displays the result of the search.
摘要:
An association dictionary creation apparatus is provided that is capable of easily and efficiently creating an association dictionary suiting the user's taste. The association dictionary creation unit includes: a profile storage unit that stores a profile which is information regarding the user's taste; a word selection unit that determines, every predetermined time, a word from the profile stored in the profile storage unit as an associated word search word, and further, selects words, other than the associated word search word, included in the profile as the associated word candidates; and an association degree calculation unit that calculates the degree of association between the associated word search word and each associated word candidate word selected by the word selection unit with reference to the contents stored in the contents storage unit, and when the association degree is higher than a predetermined threshold value, sets the associated word search word and the associated word candidate word as the associated word pair and stores the associated word pair and the association degree in the association dictionary storage unit in association with each other.
