Abstract
The disclosed embodiments provide a method, system and apparatus for processing data. During operation, the system obtains a set of content items containing unstructured data. Next, the system obtains a set of part-of-speech (POS) tags for lexical items in the set of content items. The system then uses a computer to match the POS tags to one or more POS tagging patterns to obtain a set of candidate topics for the set of content items and extract a set of topics for the set of content items from the set of candidate topics.
Claims20
A computer-implemented method for processing data, comprising:
- obtaining a set of content items comprising unstructured data;
- obtaining a set of part-of-speech (POS) tags for lexical items in the set of content items;
- and
- using a computer to:
- match the POS tags to one or more POS tagging patterns to obtain a set of candidate topics for the set of content items;
- and
- extract a set of topics for the set of content items from the set of candidate topics.
A system for processing data, comprising:
- a tagging apparatus configured to:
- obtain a set of content items comprising unstructured data;
- and
- obtain a set of part-of-speech (POS) tags for lexical items in the set of content items;
- a matching apparatus configured to match the POS tags to one or more POS tagging patterns to obtain a set of candidate topics for the set of content items;
- and
- an extraction apparatus configured to extract a set of topics for the set of content items from the set of candidate topics.
An apparatus, comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- obtain a set of content items comprising unstructured data;
- obtain a set of part-of-speech (POS) tags for lexical items in the set of content items;
- match the POS tags to one or more POS tagging patterns to obtain a set of candidate topics for the set of content items;
- and
- extract a set of topics for the set of content items from the set of candidate topics.
