Basis Technology participated in the TAC Entity-Link task of the Knowledge Base Population track at TAC 2012. We developed a supervised learning approach which produces a single model that is capable of operating across all languages and entity types. Our features are based on the outputs of other models, many of which are unsupervised.
This paper presents a novel multi-frame graph matching algorithm for reliable partial alignments among point clouds. We use this algorithm to stitch frames for 3D environment reconstruction. The idea is to utilize both descriptor similarity and mutual spatial coherency of features existed in multiple frames to match these frames. The proposed multi-frame… (More)
Modifying the surfaces of metal nanoparticles with self-assembled monolayers of functionalized thiols provides a simple and direct method to alter their surface properties. Mixed self-assembled monolayers can extend this approach since, in principle, the surfaces can be tuned by altering the proportion of each modifier that is adsorbed. However, this works… (More)
A facile total synthesis of three members of the bisabolane sesquiterpene family, namely (±)-curcumene, (±)-xanthorrhizol and (±)-curcuhydroquinone had been achieved in high overall yield. The synthesis used bromobenzene derivatives as starting materials. The halogen-lithium exchange followed by addition of isoprenylacetone and reduction of the obtained… (More)
In the title mol-ecule, C(20)H(16)O(4), the two outermost phenyl rings form dihedral angles of 79.80 (7) and 69.35 (7)° with the central benzene ring. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into ribbons propagating along [1[Formula: see text]0].
