First Claim
1. A computer system, comprising:
- a processor operable toreceive a text content comprising a plurality of terms, each term comprising one or more words or phrases;
tokenize the text content into a plurality of terms, each term comprising one or more words or phrases;
identifying a first semantic attribute or a first part of speech, wherein the first semantic attribute is selected from the group of semantic attributes consisting of at least an action, a thing, a person, an agent of an action, a recipient of an action or a thing, a state of an object, a mental state of a person, a physical state of a person, a positive or negative opinion, a name of a product, a name of a service, a name of an organization, wherein the first part of speech is selected from the group of parts of speech consisting of at least a noun or a pronoun, a transitive or intransitive verb or modal verb or link verb, an adjective, an adverb, a preposition, an article, a conjunction;
identify a first term in the text content, wherein the first term is associated with the first semantic attribute or the first part of speech;
identify a second term in the text content, wherein the second term is not associated with the first semantic attribute or the first part of speech;
associate an importance measure to the first term, based at least on the first semantic attribute or the first part of speech, to mark the first term as bearing more importance than the second term in representing a topic or an information focus in the text content;
extract the first term based on the importance measure; and
output the first term;
when the first term is output, the function of the first term includes being a tag or a label to represent a topic or a summary of the text content, or a category node;
when the first term is output and displayed, the display format includes the font type, size, color, shape, position, or orientation of the first term based on the importance measure;
when the text content containing the first term is made searchable using a query or is associated with a search index to produce a search result, the search result is ranked based at least on the importance measure.

Abstract
A computer system and methods are disclosed for automatically discovering topics and building a hierarchical topic structure, and for tagging and categorizing contents in a document or other natural language contents. The disclosed methods include steps for obtaining terms that best represent the topics in a text content, and building a hierarchical representation of topics of different levels or topic-comment relationships, and folder-subfolder structures. The methods further include obtaining, identifying, and selecting terms representing different degrees of informational importance based on the grammatical roles, parts of speech, and semantic attributes associated with the terms, using the terms to represent topics in the document, to automatically tag the document, to rank search results, and to build a category structure based on the selected terms.

10. A method implemented on a computer comprising a processor, the method comprising:
-
receiving a text content containing text; tokenizing the text content into a plurality of terms each comprising an element selected from the group of elements consisting at least of a word, a phrase, a sentence, a paragraph; identifying a first term in the text content; identifying, in at least a portion of the text content, a second term, wherein the portion of the text content contains the first term or is grammatically or semantically associated with the first term; identifying a first grammatical attribute associated with the second term, or identifying a first semantic attribute associated with the second term; selecting the second term as a term related to the first term based at least on the first grammatical attribute or the first semantic attribute; marking the first term for use as a first-level entity in a hierarchical format, and marking the second term for use as a second-level entity in the hierarchical format, wherein the second-level entity is marked as an element under or subordinate to the first-level entity; and outputting the first term and the second term to be used for at least providing a relational or hierarchical representation of the informational elements in the text content; when the first term is used to represent a first-level category node, and the second term is used to represent a second-level category node or the content of the first-level category, an embodiment format of at least one of the category nodes includes a text element, a folder or a directory, or a link name associated with the linked contents on a device selected from the group of devices consisting at least of a computer file system, an email system, a web-based or cloud-based system, a mobile or handheld computing or communication device; when the first term and the second term are displayed, a display format comprises at least representing the first term as a topic or information focus in the text content, and the second term as a comment or attribute associated with the topic or the information focus;
or representing the first term as a folder or directory in an electronic content management system, and the second term as a sub-folder or sub-directory in the electronic content management system;when the text content or the first term is made searchable using a query or is associated with a search index to produce a search result, a display format of the search result comprises the first term with one or more of its corresponding second terms if the first term matches a keyword in the search query. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
