Abstract: A technique for providing search results may include determining a first entity type, a second entity type, and a relationship type based on a compositional query. The technique may also include identifying nodes of a knowledge graph corresponding to entity references of the first entity type and entity references of the second entity type. The technique may also include determining from the knowledge graph an attribute value corresponding to the relationship type for each entity reference of the first entity type and for each entity reference of the second entity type. The technique may also include comparing the attribute value of each entity reference of the first entity type with the attribute value of each entity reference of the second entity type. The technique may also include determining one or more resultant entity references from the entity references of the first entity type based on the comparing.

Abstract: A method for preparing a tar extract with aroma characteristics from a discarded cigarette butt includes: (1) adding the discarded cigarette butt to an extraction solvent, and carrying out subcritical fluid extraction to obtain an extraction solution; (2) carrying out vacuum filtration on the extraction solution, and carrying out vacuum distillation on the filtrate to obtain a concentrated extractum; and (3) carrying out molecular distillation on the concentrated extractum, and collecting a light fraction of the molecular distillation to obtain the tar extract with aroma characteristics. Through the subcritical fluid extraction and separation by the molecular distillation to prepare the tar extract, harmful substances in the tar are removed, and the aroma components are retained. The tar extract is applied to a cigarette to improve the aroma, smoke and taste characteristics of the cigarette.

Abstract: Implementations provide an enhanced search result to improve the user search experience. For example, the result may include insightful information relevant to the search query that was not specifically requested but that the user may find interesting, such as relationships shared between the two entities related to the query, a relationship between the two entities that does not commonly occur with another relationship shared by the entities, or strong secondary connections for an entity related to the query. In some implementations, insightful connections may also be unique facts for a particular entity. Unique facts may represent a superlative attribute of an entity such as, for example, the tallest actor, the oldest president, the most expensive stock, etc. Such shared relationships, rare relationships, and/or unique facts may be provided as part of the search results presented to the query requestor and may provide insight to the requestor about the entity.

Abstract: Methods, systems, and computer-readable media are provided for related entity search. In some implementations, a search system identifies a collection of entities associated with a search query. The search system identifies entities related to those entities, and determines the relationships between them. The search system provides access to one or more collections of related results identifying entities based on the determined relationships.

Abstract: This invention relates to a piezoelectric ceramic material of a quarternary system, formulated on the basis of ternary system materials (PCM and PMN). Said quarternary system piezoelectric ceramic material consists of lead niobate with Mg (Pb (Mg.sub.1/3 Nb.sub.2/3)O.sub.3, lead niobate with Mn (Pb(Mn.sub.1/3 Nb.sub.2/3)O.sub.3), lead zirconate (PbZrO3) and lead titanate (PbTiO3), and possesses excellent properties for large power output purposes, and is suitable for making piezoelectric transformers of large power output. A single piece piezoelectric transformer (dimensions 100.times.25.times.36 mm3) using the material of the present invention is found to have a maximum output power of 50 W. The material according to this invention has a simple preparing process, a wider and lower sintering temperature range, is fine and compact in ceramic structure, and has a high rate of success of finished products.
