Information searching system
| DWPI Title: Computer-implement method for searching collection of documents, involves combining text terms and image terms to form search terms, and searching collection of documents for images in conjunction with text using searching processes |
| Abstract: A method and computer system for searching a collection of documents. The method comprises first identifying text in the document and then identifying an image in the document. Then the features of the image are extracted from the document and image terms are identified from the features. Finally, the collection of documents is searched using the image terms in conjunction with text terms. |
| Use: Computer-implement method for searching a collection of documents. |
| Advantage: The method enables facilitating a more efficient searching of documents containing text in images. The method enables providing increased accuracy for speed in searching collection of documents for both text and images. |
| Novelty: The method involves identifying text in a document (1200). Text terms are identified from the text by a processor (1202). An image in the document is identified (1204). Features in the image in the document are extracted (1206), where the features are described using descriptor vectors. Image terms for the features are identified (1208) by comparing descriptor vectors for the features to descriptor vectors representing features in a dictionary. The image is transformed into image terms. The text terms and the image terms are combined to form search terms. A collection of documents for images is searched in conjunction with text using text-only searching processes (1210). |
