Abstract: A non-transitory computer readable medium storing a program is provided. A process of the program includes: extracting, concerning first document information including texts, a word sense associated with a word in each text; setting a word sense to be a teacher signal; creating a first topic model by using the teacher signal; estimating a topic of each text by using the first topic model; generating a learning model by using the topic as a feature and the teacher signal as a category; extracting, concerning second document information including texts, a word sense associated with a word in each text; setting a word sense to be a teacher signal; creating a second topic model by using the teacher signal; estimating a topic of each text by using the second topic model; and estimating a category of each text by using the topic as a feature and the learning model.

Abstract: Provided is a non-transitory computer readable medium storing a document creation support program causing a computer to function as a receiving unit that receives a defined text and edition process information having recorded therein an operation history when creating the defined text including a sentence associated with the operation, a revision range extraction unit that extracts, as a revision range, an operation history corresponding to a preset operation and a sentence associated with the operation history from the edition process information, a document feature quantity extraction unit that extracts first and second feature quantities, and a sentence example information search unit that searches for a sentence example associated with a sentence in sentence example information having a sentence example registered in advance in association with feature quantity information of the sentence example on the basis of information of the first and second feature quantities.

Abstract: An information processing apparatus includes a receiving unit, a determining unit, a first assigning unit, an extracting unit, a second assigning unit, a modeling unit, and an output unit. The receiving unit receives a target character string. The determining unit determines whether a sentiment character string is included in the received character string. A first assigning unit assigns a label corresponding to a sentiment character string to the character string when the sentiment character string is included, and assigns plural labels to the character string when no sentiment character string is included. The extracting unit extracts a word from the character string. The second assigning unit assigns to the extracted word a label which has been assigned to the character string that includes the word. The modeling unit performs supervised topic modeling for the character string. The output unit outputs a result of a process by the modeling unit.

Abstract: A non-transitory computer readable medium stores an annotation-information adding program that causes a computer to function as an adding unit, an evaluating unit, and a setting unit. The adding unit adds annotation information to target information including multiple targets based on input from a first inputter. The evaluating unit evaluates reliability of the first inputter and reliability of a second inputter by comparing annotation information already added to at least one of the multiple targets by the second inputter with annotation information added by the first inputter. The setting unit sets a target range in the target information intended for requesting the first inputter to add annotation information based on the reliability of the first inputter and the reliability of the second inputter.
