Abstract: A system, method, and computer program product are configured to extract key value pair (KVP) data from one or more documents; obtain a content index for the one or more documents; and enhance the content index with the KVP data to provide a KVP content index.

Abstract: Disclosed embodiments provide techniques for creating a smaller version of an original document. An ontology is defined, and a document type for an original document is determined, based on the ontology. Multiple key-value pairs (KVPs) are extracted from the original document based on the document type. Pages in the original document that include one or more KVPs are identified, and the smaller, condensed version includes the identified pages from the original document.

Abstract: A high-efficiency and multifunctional sludge conditioner and a preparation method thereof is disclosed. The preparation method includes: soaking and adsorbing bacterial cellulose in an alkaline solution, and then taking out the bacterial cellulose to carbonize and activate the same at 380-480° C. and in a nitrogen atmosphere to obtain pretreated bacterial cellulose; and dispersing the pretreated bacterial cellulose in water, adding with an acrylamide monomer and an initiator for in-situ polymerization, and successively subjecting a reaction product to centrifugal separation, drying and crushing to obtain the high-efficiency and multifunctional sludge conditioner.

Abstract: A computer-implemented method for text block segmentation includes determining a first text block segmentation pattern utilized to generate a segmented text block based, at least in part, on a comparison of semantic information associated with the segmented text block and a plurality of predefined types of text block segmentation patterns indicated by a graph; calculating a first degree of confidence in a size of the segmented text block based, at least in part, on comparing semantic entities associated with the segmented text block with semantic entities indicated by leaf nodes stemming from a first non-leaf node included in the graph and representative of the first type of text block segmentation pattern; and determining that the size of the segmented text block is non-optimal based on the calculated degree of confidence in the size of the segmented text block being below a predetermined threshold.

Abstract: A method, computer system, and a computer program product is provided for generating a detailed thumbnail and/or preview of a content. In one embodiment the technique comprises analyzing data obtained from a content and classifying it according to a plurality of specific types. A plurality of key information may be then extracted from the data according to the classification. A plurality of key-values are correlated to the plurality of key information so as to provide a plurality of key-value pairs. These pairs are consolidated accordingly to generate a thumbnail and/or a preview that at least renders the key information provided by the consolidated key-value pairs as a rendering.

Abstract: A press-fit wire disposed in a magnetic device is provided. The press-fit wire includes a first wire and a second wire. The second wire is attached to the first wire. The first wire and the second wire are arranged along a first direction and are parallel circuits. The first wire and/or the second wire is a multi-strand wire.

Abstract: Various embodiments include a testing apparatus capable of testing gas flowing in a duct. The apparatus may include: a housing; a sampling tube extending from the housing to be inserted into the duct, the sampling tube including a gas entry channel and a gas exit channel isolated from each other, with a gas inlet of the gas entry channel and a gas outlet of the gas exit channel disposed in a part of the sampling tube leading into the duct and disposed at the same side of the sampling tube, wherein the gas inlet and the gas outlet have matching gas through-flow areas; and a sensor module disposed in the housing and in gas communication with the gas entry channel to test gas sampled from the gas entry channel.

Abstract: A process for producing nano veneers generally involving: placing a veneer to be treated in a vacuum vessel; adding a nano carbon powder and nano silicon dioxide suspension in the vacuum vessel; reducing the pressure in the vessel over a first period of time; increasing the pressure in the vessel; letting the contents of the vessel rest over a second period of time. The veneer may optionally be subjected to ultrasonic treatment, ultraviolet solidification treatment, or subsequent pressurization treatments to obtain the final nano veneer product. As a result, veneer manufactured using embodiments of the present invention will have the advantages of high strength, wear resistance, pollution resistance, acid and alkali resistance, water segregation and decay resistance.
