A method and apparatus for generating information are disclosed. An implementation of the method includes: receiving a target text, the target text including an objective and descriptive information of the objective; performing a dependency syntax parsing on the target text to generate a dependency tree of the target text; matching predetermined syntactic structure tree with the dependency tree to obtain at least one triple, a triple including a subject, a predicate, and an object; and determining, based on words contained in a triple among the at least one triple and a predetermined weight of the syntactic structure tree matched to obtain the triple, a target triple among the at least one triple.

Method and apparatus for generating information

A method and an apparatus for event detection, a device, and a storage medium. An event is formed by acquiring a plurality of texts including a target keyword; extracting phrases independently describing event information from titles of the plurality of texts; and clustering the extracted phrases and gathering texts where phrases belonging to a same cluster are located to form an event. The accuracy of the event detection and the recall rate for an event can be improved through the method provided by embodiments of the present application.

A carbon fiber arrow shaft comprises a hollow tube, a reinforced carbon fiber, and a resinoid binder. The hollow tube has a length between 500-900 mm, an inner diameter between 2-10 mm, and a tube wall thickness between 0.3-2 mm. The reinforced carbon fiber and the resinoid binder form a resin-impregnated carbon fiber. The carbon fiber arrow shaft is formed by directly and continuously winding the resin-impregnated carbon fiber around the hollow tube. The carbon fiber arrow shaft has a head section (L,), a middle section (L,) and a tail section (L,). A winding angle of the carbon fiber at the head section (L,) is changed from a larger winding angle to a smaller winding angle, a winding angle at the middle section (L,) stays constant, and a winding angle at the tail section (L,) is changed from a smaller winding angle to a larger winding angle. The lengths of the head section (L,) and the tail section (L,) are between 25-250 mm. The initial winding angle at the head section (L,) is between 30-90 degrees and is gradually decreased to between 2-30 degrees at the boundary of the head section (L,) and the middle section (L,). The winding angle at the middle section (L,) stays constant, and the winding angle at the tail section (L,) is gradually increased from between 2-30 degrees at the boundary of the middle section (L,) and the tail section to between 30-90 degrees at the end of the tail section (L,). The peripherally located winding angles at both the head section (L,) and the tail section (L,) are at least two times the winding angle at the middle section (L,). The shaft provides uniformity of wall thickness and eliminates overlapping joints or surface protrusions.
