Do Structurally Similar Ligands Bind in a Similar Fashion?

Journal of Medicinal Chemistry, 2006
The scope of the current work is to investigate whether structurally similar ligands bind in a similar fashion by exhaustively analyzing experimental data from the protein database (PDB). The complete PDB was searched for pairs of structurally similar ligands binding to the same biological target.

Sentence Similarity on Structural Representations

2016
Most previous approaches used various kinds of plain similarity features to represent the similarity of a sentence pair, and one of its limitations is its weak representation ability. This paper introduces the relational structures representation (shallow syntactic tree, dependency tree) to compute sentence similarity.

Similarity ranking technique exploiting the structure of similarity relationships

Computing, 2020
This paper proposes a similarity ranking technique that exploits the entire network structure of similarity relationships for multimedia, particularly image, databases. The main problem in the similarity ranking on multimedia is the meaning gap between the characteristics automatically computed from the multimedia dataset and the interpretation by ...

Similarity measures for structured representations

1994
A key concept in case-based reasoning is similarity. In this paper, we first propose a similarity measure for structured representations that is based on graph edit operations. Then we show how this similarity measure can be computed by means of state space search.

Learnability and Definability in Trees and Similar Structures

Theory of Computing Systems, 2002
The problem of concept learning is to identify an unknown set from a given family of sets. A universe is a nonempty finite set \(A\). A vocabulary \(\tau\) is a finite set of predicates defined on \(A\). A structure is the pair (\(A,\tau\)). An atomic formula is \({x = y}\) or \({R(x_1,\dots ,x_r)}\), where \({R \in \tau}\).

Beyond topical similarity: a structural similarity measure for retrieving highly similar documents

Knowledge and Information Systems, 2006
Accurately measuring document similarity is important for many text applications, e.g. document similarity search, document recommendation, etc. Most traditional similarity measures are based only on “bag of words” of documents and can well evaluate document topical similarity.
