Entity Linking for Queries by Searching Wikipedia Sentences
We present a simple yet effective approach for linking entities in queries.
The key idea is to search sentences similar to a query from Wikipedia articles
and directly use the human-annotated entities in the similar sentences as
candidate entities for the query. Then, we employ a rich set of features, such
as link-probability, context-matching, word embeddings, and relatedness among
candidate entities as well as their related entities, to rank the candidates
under a regression based framework. The advantages of our approach lie in two
aspects, which contribute to the ranking process and final linking result.
First, it can greatly reduce the number of candidate entities by filtering out
irrelevant entities with the words in the query. Second, we can obtain the
query sensitive prior probability in addition to the static link-probability
derived from all Wikipedia articles. We conduct experiments on two benchmark
datasets on entity linking for queries, namely the ERD14 dataset and the GERDAQ
dataset. Experimental results show that our method outperforms state-of-the-art
systems and yields 75.0% in F1 on the ERD14 dataset and 56.9% on the GERDAQ
dataset
Integrated urban water management in Texas: a review to inform a one water approach for the future
Texas has considerable experience grappling with historic droughts as well as flooding
associated with tropical storms and hurricanes, yet the State’s water management challenges
are projected to increase. Urban densification, increased frequency and severity of droughts
and floods, aging infrastructure, and a management system that is not reflective of the true
cost of water all influence water risk. Integrated urban water management strategies, like ‘One
Water’, represent an emerging management paradigm that emphasizes the interconnectedness
of water throughout the water cycle and capitalizes on opportunities that arise from this
holistic viewpoint. Here, we review water management practices in five Texas cities and
examine how the One Water approach could represent a viable framework to maintain a
reliable, sustainable, and affordable water supply for the future. We also examine financial and
business models that establish a foundational pathway towards the ‘utility of the future’ and
the One Water paradigm more broadly
The roles of inter- and intra-sexual selection in behavioral isolation between native and invasive pupfishes
Male-male competition and female mate choice may both play important roles in driving and maintaining reproductive isolation between species. When previously allopatric species come into secondary contact with each other due to introductions, they provide an opportunity to evaluate the identity and strength of reproductive isolating mechanisms. If reproductive isolation is not maintained, hybridization may occur. We examined how reproductive isolating mechanisms mediate hybridization between endemic populations of the Red River pupfish Cyprinodon rubrofluviatilis and the recently introduced sheepshead minnow C. variegatus. In lab-based dominance trials, males of both species won the same number of competitions. However, male C. rubrofluviatilis that won competitions were more aggressive than C. variegatus winners, and more aggression was needed to win against competitor C. variagatus than allopatric C. rubrofluviatilis. Duration of fights also differed based on the relatedness of the competitor. In dichotomous mate choice trials, there were no conspecific or heterospecific preferences expressed by females of either species. Our findings that male-male aggression differs between closely and distantly related groups, but female choice does not suggest that male-male competition may be the more likely mechanism to impede gene flow in this system
