Entity attribute extraction is the process of identifying and extracting attributes, or characteristics, of entities from a given text. The objective is to create a model that can automatically perform person-attribute information extraction from unstructured text. Entity attribute extraction's primary goal is to locate and extract attributes of entities from a supplied text. As a result, information from the unstructured text may now be represented in a structured way. By extracting attributes of entities, a computer program can gain a better understanding of the information contained in the text and can use this information for various purposes such as building a knowledge base or for information retrieval. In this way, entity attribute extraction can help to improve the ability of computer programs to process and understand natural language text. All the essential tools and algorithms are researched and discussed in this paper. This study is divided into two main sections that explore published works and modern tools and technologies working in the field of Entity attribute extraction. It also identifies critical research gaps in the literature under assessment. The gap analysis reveals potential for improved textual event prediction algorithms in the future.

It is often necessary to cross a river or any other obstacle where no bridges exist or they have been collapsed due to natural disasters. In general already prefabricated bridge elements will be used. They are mostly made out of light as well transportable and detachable parts from high quality materials which could be fast to build Bridges with different span, width and load capacity. In the present paper behavior and performance of a Bridge, using three different types of truss members, namely Isotruss member, Box section and Circular tube, have been studied. Bridge is modelled and analysed using commercial Finite Element (FE) software. The Bridge is designed for a span of 10.50 m. Live load of 4 KN/m2 and wind load of 51.15 N, 70.34 N and 56.17 N applied as point load on Isotruss, Circular tube and Box section respectively are applied for designing the truss members. For serviceability condition stresses as well as deflections in members have been checked.

The search for lightweight and highly efficient structural components is a continuing process. Reducing the structural weight and improving the load carrying capabilities of these structures will allow designers to append additional capabilities while reducing cost. Isogrid is a lattice of stiffened ribs forming an array of contiguous equilateral triangles. This rib pattern forms triangular trusses by maintaining isotropic property. Ribs when arranged in 60? pattern are known as Isogrid. The highly redundant nature of Isogrid stiffening concept provides high efficiency distributing loads and is less susceptible to impact damage, delamination, and crack propagation. Isogrid structure is typically found in stiffness critical components that resist buckling. The behavior and performance of Isogrid deck slab in a Bridge supported by the truss girders is studied. Isogrid is modeled, analyzed and designed using commercial Finite Element (FE) software. In the present work, a truss bridge is designed for a span of 10.305 m. The bridge is designed using three different kinds of deck configuration, rectangular section without skin, inverted T section with skin, and I section with skin. Commercial FE software is used for computing deflections and stresses. It is found that the deck profile of I section with skin is more preferable than other configurations for Truss Bridge.
