Abstract: Embodiments of the present disclosure relate to a method and apparatus for document retrieval. The method comprises: determining, in response to receiving a request to retrieve a document from a user, information for the user; obtaining, based on the determined information, ACL information for the user from an ACL index, the ACL index indicating access right of at least one user to the document; and determining, based on the ACL information of the user, a document to be provided to the user from retrieved documents in response to the request. According to the embodiments of the present disclosure, the retrieval efficiency may be enhanced.

Abstract: A method and apparatus for providing access to content resources are provided. The method comprises: in response to receiving a first request for accessing first content resources in a content server, obtaining from the content server metadata associated with a first Uniform Resource Identifier (URI) of the first content resources, the first request including the first URI, the metadata at least indicating a mapping between the first URI of the first content resources and a second URI of the first content resources, the first URI being a shortened version of the second URI; obtaining the second URI by parsing the metadata; and responding to the first request with the second URI of the first content resources.

Abstract: Various embodiments of the present disclosure provide a solution for category-based full-text searching. In some embodiments, there is provided a method of full-text searching. The method includes generating a first full-text index based on an obtained electronic document content. The method also includes categorizing the electronic document to determine a category identifier for the electronic document, and generating a second full-text index based on the category identifier. The method further includes storing the first full-text index and the second full-text index.

Abstract: Various embodiments of the present disclosure provide a solution for converging a data management system and a data analysis system at the level of storage. In some embodiments, the present disclosure provides a computer-implemented method. The method includes obtaining, a data management system, a first file in a first format. The method also includes, in response to determining that the first format is different from a predetermined second format supported by a data analysis system, converting the first file into a second file in the second format. The method further includes storing the first and second files to a data storage system. The data storage system is accessible to the data management system and the data analysis system.

Abstract: A method and apparatus for data processing including receiving a data loading request from a data processor; in response to receiving the data loading request, obtaining requested raw data from a data memory; in response to the raw data being unstructured data, extracting, textual data from the raw data with a text extractor associated with a file type of the raw data; and transmitting the textual data to the data processor. Various embodiments can employ a uniform flow to process structured data and unstructured data. Through the uniform flow, textual information included in the unstructured data can be extracted in real time. Analysis of association between the text and the unstructured data can be performed conveniently in a same analysis task.
