Abstract: A fixing structure, configured to fix screw. Screw includes wide portion and narrow portion. Fixing structure includes plate part, holding component and elastic positioning component. Plate part includes top surface, bottom surface and mount groove. Mount groove penetrates through top surface and bottom surface and narrow portion is disposed through mount groove to allow wide portion to rest on top surface. Holding component and top surface together form space. Elastic positioning component is disposed on plate part. When wide portion is located in space and between holding component and top surface, and elastic positioning component is in holding state and located at side of wide portion, wide portion is prevented from being moved away from space. When elastic positioning component is switched to released state, elastic positioning component is removed from side of wide portion so that wide portion is allowed to move away from space.

Abstract: A server including chassis, motherboard, mounting cage, first guide pillar and expansion card. Motherboard is stacked on chassis bottom plate. Mounting cage includes bearing base, handle and first pivot. Bearing base is located on a side of motherboard located away from the chassis bottom plate and located between two chassis side plates. One of two bearing base side plates includes first guide slot, and handle is pivotally connected to the one of two bearing base side plates via first pivot and includes engagement hole. First guide pillar is fixed to the one of two chassis side plates and slidably disposed in first guide slot of the one of two chassis side plates. First guide pillar is engaged into engagement hole of handle. Expansion card is stacked on bearing base bottom plate and electrically connected to motherboard.

Abstract: The invention provides a motherboard assembly. The motherboard assembly includes a circuit board, an expansion card connector, an expansion card assembly, a bracket and a fastener. The expansion card connector is disposed on the circuit board. The expansion card assembly includes a cage, an adapter card, and at least one expansion card. The adapter card is installed on the cage and includes an electrical connector. The electrical connector is inserted into the expansion card connector, and the expansion card is installed on the adapter card. The bracket includes a first mount plate and a second mount plate connected to each other. The first mount plate is fixed on the circuit board, and the second mount plate is located farther away from the circuit board than the first mount plate. The fastener is disposed through the cage and screwed into the second mount plate of the bracket.

Abstract: An electronic device comprises a housing, and a fan connection member. The housing comprises a bottom plate having a motherboard mounting area. The fan connection member is disposed on the bottom plate, and an orthogonal projection of the fan connection member onto the bottom plate partially overlaps with the motherboard mounting area. The fan connection member includes a fan base and a fan seat pivoted on the fan base. The orthogonal projection of the fan connection member has a first overlap area on the motherboard mounting area at a working state of the fan connection member. The orthogonal projection of the fan connection member has a second overlap area on the motherboard mounting area at a maintenance state of the fan connecting member. The first overlap area is larger than the second overlap area.

Abstract: A scoring method includes steps of: storing a word list in a database of a computer; storing word vector combinations in the database; extracting a keyword from a submitted answer, and looking up, in the word list, a word vector that corresponds to a word which conforms with the keyword; and obtaining, from the database, one of the word vector combinations, and calculating, for each of benchmark nouns of the one of the word vector combinations thus obtained, a semantic distance between the keyword and the benchmark noun based on word vectors respectively corresponding to the keyword and the benchmark noun, and calculating an originality score based on the semantic distances of the respective benchmark nouns thus calculated.

Abstract: An automated website data collection method uses a hybrid web crawler strategy to obtain a probability distribution of a webpage tag of a webpage of a website to obtains an important feature of the website, and then extracts a text content of important features of the website, and forms a seed vocabulary data set using a composite semantic model. A thematic vocabulary data set having high frequency and highly representative hierarchical structure is further generated by the seed vocabulary data set, and the thematic vocabulary data can be further presented by the visualized system to show the hierarchical structure of thematic vocabulary data set.

Abstract: EMI-proof server chassis preventing EMI on an electronic component, includes a chassis and a double aperture flexible piece. The chassis includes a connection portion connected to the chassis, a first engagement portion and a second engagement portion. The first engagement portion and the second engagement portion are connected to and disposed on two sides of the connection portion. The first engagement portion and the second engagement portion are parallelly prolonged, and substantially opposite to each other. The double aperture flexible piece, shaped as a curvature plate, has a first aperture and a second aperture on two sides. The first engagement portion and the second engagement portion are engaged to the first aperture and the second aperture respectively, and the portion of the double aperture flexible piece between the first aperture and the second aperture is curved toward the electronic component, and contact with the electronic component.
