Japanese Named Entity Extraction API
2015/11/03
By using Japanese Named Entity Extraction API, you can create an application which extracts "named entities", such as a person name or location name, from Japanese strings.
Overview: Japanese Named Entity Extraction API
Japanese Named Entity Extraction API extracts "named entities", such as person names, location names, and so on, from the sent-in Japanese strings.
In the case of the sent-in Japanese string is "鈴木さんがきょうの9時30分に横浜に行きます。" (Mr. Suzuki goes to Yokohama at today's 9:30.), "鈴木"(Mr. Suzuki), "横浜"(Yokohama), "きょう"(today) and "9時30分"(9:30) are extracted. "鈴木"(Mr. Suzuki) is a person name, "横浜"(Yokohama) is a location name, "きょう"(today) is a date expression and "9時30分"(9:30) is a time expression.
This API also extracts organization names, such as "XYZ corporation", and artifact names, such as "AAA building".
Those named entity words are useful when extracting the marketing data on the web. It makes easier to finding this week's hot location from SNS posts.
