Abstract: An information searching method and an information searching device are provided. The information searching method includes: receiving, at one or more computing devices, a first query from a client device, and obtaining, at the one or more computing devices an intention clarification guidance sentence according to the first query; receiving a second query updated according to the intention clarification guidance sentence; obtaining a search result according to the second query; and returning the search result to the client device.

Abstract: An interactive searching method and apparatus are provided. The interactive searching method includes following steps. A first query is received, an intention clarification guidance sentence is obtained according to the first query, a feedback corresponding to the intention clarification guidance sentence is received, a second query is generated according to the first query, the intention clarification guidance sentence and the feedback, and a search result is provided according to the second query.

Abstract: An interactive searching method and an interactive searching apparatus are provided. The interactive searching method includes following steps. A first query is obtained by a search engine, and a first parsing result of the first query is obtained by the search engine and a first search result associated with the first query is obtained according to the first parsing result and is returned by the search engine.

Abstract: A system and a method for remediation of organic contaminated soil are provided, which comprises M*N electrodes to form an electrode matrix of symmetrical electric field structure. The field intensity is uniform in those points that are equidistant from each electrode in remediation area. The electrodes arrayed in mesh style in remediation area are carried out electrokinetic remediation. To exchange between positive polarity and negative polarity of the electrodes periodically is to make each electrode be a state of anode intermittently which has preferable remediation efficiency, by operation mode of reversing row/column electrode groups in manner of electrical scanning.

Abstract: A valuable document identification method and system are provided. The method comprises, detecting features in different space ranges of a valuable document, and obtaining multi-source information ?={Xi, Xj, . . . , Xn}, wherein Xi?Xj??, or Xi?Xj?? and Xi<=>Xj; labeling the space position of Xj with Xi according to semantic constraints of Xi and Xj, and obtaining position constraints ?ij(x, y); extracting a characteristic value fi from Xi, and extracting a characteristic value fj from Xj according to the position constrains ?ij(x, y); determining whether fi, fj meet the characteristic criteria of the valuable document, if yes, then receiving the valuable document, or else, rejecting the valuable document. The method enables improved reliability and robustness of the valuable document identification system.
