Described is processing a web query into structured data, such as for use in formulating a database query. A classifier and segmental conditional random field (CRF) model classify and segment a query into labeled segments used to obtain the structured data. The structured data includes a class, an intent set corresponding to data sought by the query, and an attribute set corresponding to an attribute name and attribute value representing each modifier in the query. The structured data may be converted into a query language (e.g., SQL) query to query the structured data source; e.g., the class may be used to select a database, the attribute set used to find one or more columns and a row in the database, and the intent set matched to a column, whose row data is the result being sought. A web search engine may return the database query as part of its results. |
