Abstract

There are provided a method for managing and searching information in a mobile terminal and methodology for constructing the method. The method comprises: when a text is provided, preprocessing the provided text; extracting anchor text candidates in the preprocessed text; calculating relatedness between terms; determining ranking based on the relatedness using context information; and constructing a hypertext system for providing hypertext links to the provided text based on the ranking. Accordingly, there is provided a method for providing hypertext links in a mobile terminal, which provides information management and search function using the hypertext links, so that information in the mobile terminal can be constructed by the hypertext links, thereby promoting user'"'"'s convenience.

Claims

1. A method for providing hypertext links in a mobile terminal, the method comprising:

when a text is provided, preprocessing the provided text;

extracting anchor text candidates in the preprocessed text;

calculating relatedness between terms;

determining ranking based on the relatedness using context information; and

constructing a hypertext system for providing hypertext links to the provided text based on the ranking, such that the hypertext links provide search functions based on at least a portion of the provided text.

2. The method according to claim 1, wherein preprocessing of the provided text is to parse the text by performing processes including part-of-speech tagging, stopword removal and named entity recognition.

3. The method according to claim 1, wherein extracting the anchor text candidates in the preprocessed text is to classify preprocessed results into one or more categories.

4. The method according to claim 3, wherein, in the extraction of the anchor text candidates in the preprocessed text, the preprocessed results are classified into five categories including person or group name, place name, activity or event name, time expression and theme.

5. The method according to claim 4, wherein the preprocessed results are classified into five categories by a rule-based classifier based on vocabulary-dictionary, using named entity recognition.

6. The method according to claim 1, wherein the calculation of the relatedness of the vocabulary belonging to the anchor text candidates is to compare a vocabulary belonging to the anchor text candidates with existing information stored in the mobile terminal and calculate relatedness value.

7. The method according to claim 1, wherein the determination of the ranking based on the relatedness using the context information is to determine ranking using context information on time.

8. The method according to claim 1, wherein the determination of the ranking based on the relatedness using the context information is to determine ranking using context information on place.

9. The method according to claim 1, wherein the construction of the hypertext system for providing the hypertext links to the provided text based on the ranking is to provide a hypertext link to a term with related information in the provided text.

10. The method according to claim 9, wherein in the constructing of the hypertext system for providing the hypertext links to the provided text based on the ranking, when a term in the provided text has two or more pieces of related information, a list of the related information is displayed.

11. The method according to claim 10, wherein the list of the related information has an order determined by the ranking based on the relatedness of terms and context information.

12. The method according to claim 9, wherein the related information contains information included in a short message service (SMS), information included in a mailing service, information included in a schedule service and information included in a photo gallery service.
