  • In this work, the problem of extracting phrase translation is formulated as an information retrieval process implemented with a log-linear model aiming for a balanced precision and recall. We present a generic phrase training algorithm which is parameterized with feature functions and can be optimized jointly with the translation engine to directly maximize the end-to-end system performance. Multiple data-driven feature functions are proposed to capture the quality and confidence of phrases and phrase pairs.

  • This paper proposes a novel method that exploits multiple resources to improve statistical machine translation (SMT) based paraphrasing. In detail, a phrasal paraphrase table and a feature function are derived from each resource, which are then combined in a log-linear SMT model for sentence-level paraphrase generation. Experimental results show that the SMT-based paraphrasing model can be enhanced using multiple resources. The phrase-level and sentence-level precision of the generated paraphrases are above 60% and 55%, respectively.

  • In a normalized database, the data to be viewed can be stored in multiple tables. When you need to view data from related tables together, you can query the data by joining the tables with the help of common attributes. You can also use subqueries where the result of a query is used as an input for the condition of another query. This chapter discusses how to query data from multiple tables by applying various types of joins, such as an inner join, outer join, cross join, equi join, or self join. Further, it explains how to use subqueries....

  • PULLING DATA FROM MULTIPLE TABLES " The first tag is hard-coded with the label Select image, and its value is set to an empty string. The remaining tags are populated by a while loop that extracts each record to an array called $row. A conditional statement checks whether the current image_id is the same as the one already stored in the articles table. If it is, selected is inserted into the tag so that it displays the correct value in the drop-down menu. Make sure you don t omit the third character in the...

  • Chapter 16 Managing Multiple Database Tables The previous chapter showed you how to use INNER JOIN and LEFT JOIN to retrieve information stored in multiple tables. You also learned how to link existing tables by adding an extra column to the child table and updating each record individually to insert a foreign key. However, most of the time, you ll want to insert data simultaneously in both tables. That presents a problem, because INSERT commands can operate on only one table at a time.

  • A materialized view (MV) is a more complex physical design structure than an index since a materialized view may be defined over multiple tables, and can involve selection, projection, join and group by. This richness of structure of MVs makes the problem of selecting materialized views significantly more complex than that of index selection. First, for a given query (and hence workload) the space of materialized views that must be considered is much larger than the space of indexes. For example, MVs on any subset of tables referenced in the query may be relevant.

  • Read-Only Transactions By default, Oracle guarantees statement-level read consistency. The set of data returned by a single query is consistent with respect to a single point in time. However, in some situations, you might also require transaction-level read consistency. This is the ability to run multiple queries within a single transaction, all of which are read-consistent with respect to the same point in time, so that queries in this transaction do not see the effects of intervening committed transactions.

  • Limited floor space and smaller fiber counts often dictate that multiple pieces of communications apparatus share common equipment racks. The FL1000 is designed to be mounted within standard 19" or 23" EIA equipment racks. Standard flush mount capability also makes this panel well-suited to cabinet installations. The left/right orientation of the individual angled adapters and retainers allows the easy exit of the jumpers from the panel. A removable rear door on the 24 termination panels allows efficient access the interior of the panel for the routing and termination of fiber cables.
