algorithm. The outcome of which is the further source of fuel for Bio inspired Fuzzy PSO to find the optimal
attractive points for the web documents to get clustered meeting the requirement of the search query
without losing the relevance. On the whole the proposed system optimizes the objective function of
minimizing the intra cluster differences and maximizes the inter cluster distances along with retention of all
possible relationships with the search context intact. The major contribution being the system finds all
possible combinations matching the user search transaction and thereby making the system more
meaningful. These relatable sets form the set of particles for Fuzzy Clustering as well as PSO and thus

behaviour’s evaluations reveals the proposed methodology fares well as an optimized and effective
enhancements over the conventional approaches.
Often when writing tests with Espresso you find a lot of onView, withId, perform calls scattered throughout your test methods. This takes away from the simplicity of the test, tends to be verbose and also litters resource ids everywhere. There's got to be a better way, right? Yes, there is...Screen Robots. In this presentation you will learn how to take advantage of the Screen Robot abstraction technique.

A COMPARISON OF DOCUMENT SIMILARITY ALGORITHMSgerogepatton
Document similarity is an important part of Natural Language Processing and is most commonly used for
plagiarism-detection and text summarization. Thus, finding the overall most effective document similarity
algorithm could have a major positive impact on the field of Natural Language Processing. This report sets
out to examine the numerous document similarity algorithms, and determine which ones are the most
useful. It addresses the most effective document similarity algorithm by categorizing them into 3 types of
document similarity algorithms: statistical algorithms, neural networks, and corpus/knowledge-based
algorithms. The most effective algorithms in each category are also compared in our work using a series of
benchmark datasets and evaluations that test every possible area that each algorithm could be used in.

Opinion mining is nothing but mining opinion target s and opinion words from online reviews. To find op inion relation among them partially supervised word align ment model have used. To find confidence of each candidate graph based co-ranking algorithm have used. Further candidates having confidence higher than threshold value are extracted as opinion word or opinion targets. Compa red to previous approach syntax-based method this m ethod can give correct results by eliminating parsing errors and can work on reviews in informal language. Compa red to nearest neighbor method this method can give more p recise results and can find relations within a long span. Also to decrease error propagation graph based co-r anking algorithm is used to collectively extract op inion targets and opinion words. Also to decrease probability of error generation penetration of high degree vertice s is done and decrease effect of random walk.

Recommending Scientific Papers: Investigating the User CurriculumJonathas Magalhães
In this paper, we propose a Personalized Paper Recommender System, a new user-paper based approach that takes into consideration the user academic curriculum vitae. To build the user profiles, we use a Brazilian academic platform called CV-Lattes. Furthermore, we examine some issues related to user profiling, such as (i) we define and compare different strategies to build and represent the user profiles, using terms and using concepts; (ii) we verify how much past information of a user is required to provide good recommendations; (iii) we compare our approaches with the state-of-art in paper recommendation using the CV-Lattes. To validate our strategies, we conduct a user study experiment involving 30 users in the Computer Science domain. Our results show that (i) our approaches outperform the state-of-art in CV-Lattes; (ii) concepts profiles are comparable with the terms profiles; (iii) analyzing the content of the past four years for terms profiles and five years for concepts profiles achieved the best results; and (iv) terms profiles provide better results but they are slower than concepts profiles, thus, if the system needs real time recommendations, concepts profiles are better.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

4. Relationship Extraction
• The task of recognizing the assertion of a
particular relationship between two or more
entities in text.
• Can aid in the development of
standalone, intelligent, automated and adaptable
user-specific content retrieval systems.
• We focus on extracting treatment relationships
→ A (subject) used to treat B (object).
5. Goals and Contributions
• Extended state-of-the-art Espresso relationship
extraction system originally implemented by
Ganapathi.
• Did an in-depth experimental evaluation of the
developed system while comparing it to prior
work (Chu, Ganapathi).
• Future goal is to use the system developed here
as a plug for relationship feature extractor in
iScore.
6. Integration Into iScore
• iScore presents additional articles based on an
aggregate score of “interestingness.”
• We believe filtering articles based on
relationships can improve the results of iScore.
• We hypothesize that extending the Espresso
system implemented by Swathi Ganapathi will
improve the ability of a system such as iScore to
utilize relationship extraction as a feature.
7. Comparison Criteria
• Performance: Want system to have high
precision and recall
• Minimal Supervision: Want system to require
little to no human supervision
• Breadth: Want system to extract relations from
varying corpus sizes, domains and formats.
• Generality: Want system to extract wide variety
of relation types without losing its edge in any of
the above criteria.
8. The Espresso Algorithm
• General purpose algorithm which can be used to
extract a wide variety of binary relations.
• Requires minimal supervision. Only input is a
small seed set of known relations.
• By looking at individual sentences in detecting
relationships, works well on all kinds of corpora.
• On tests conducted by the creators of the
algorithm, Espresso generated balanced
precision and recall.
11. Ganapathi's Implementation
• Ganapathi's approach uses lexico-syntactic
patterns of the form NP1 VP NP2 (Verb category
in Table 1).
• VP contains treatment verb or pattern and the
two NPs would contain the subject and object.
• This structure is a very common
relationship, accounting for 37.8% of all
relationships.
12. Extension
• There still remains a large number of
relationships that may provide fruitful results.
• Expanding the implementation to include:
- Noun+Prep e.g. "X settlement with Y"
- Verb+Prep e.g. "X moved to Y"
- Infinitive e.g. "X plans to acquire Y" and
- Modifier e.g. "X is Y winner" relationship
• Retrieves 91.2% of common relationships.

o 50,000 drug patent documents from 2008 from Class 424 & 514 of
the U.S. Patents Classification: “drug, bio-affecting and body
treating compositions” and their subclasses.
o Patents were pre-filtered to only contain keywords
“diabetes”, “metastatic”, “cancer”, “tuberculosis”, “lung”, “bronchitis”,
“coronary artery”
o All sentences from each document added to a sentence table in the
schema
• PubMed Corpus: Developed by Gustavo
o Comprised of medical abstracts from PubMed
o Each abstract was parsed and all sentences from each abstract
was stored as individual tuples in the sentence table
16. Procedure
1.Re-tag original data set to incorporate extended
relationship types.
2.Re-run Ganapathi's baseline Espresso
implementation to compare against updated data
set.
3.Run extended Espresso implementation to
compare against updated data set.
17. Experiment #1: Extraction on Drug
Patent Corpus
• Drug Patent corpus used.
• Algorithm was run with seed relations and 12 verbs were extracted as
being relevant (verbs with rπ greater than 0.2).
• These treatment verbs were used to create a test sentence set of 120
sentences i.e. 10 sentences containing a treatment verb for every
relevant treatment verb.
• 358 possible relations were extracted for each of which we calculated
the ri score.
• 208 relations were obtained with ri score greater than the threshold out
of which 126 were actually correct (through manual tagging).
• Of the original 358 relations, manual tagging determined that 213 of
them were correct treatment relations.
19. Experiment #2: Number of
Relationships and Performance
• Drug Patent corpus used.
• Test the performance of the system under
smaller and larger data loads.
• Started with initial set of 120 sentences obtained
from Drug Patent corpus (10 sentences for each
verb, 12 verbs as in test #1)
• Increased the number of sentences for each
verb by 10 in each case, so that we had
sentence sets of 240 and 360 sentences each
21. Experiment #2 Analysis
• Performance of the system and the number of
relationships are inversely related.
• ri scores are affected inversely by the max pmi across
all relationship instances, it is possible that having more
relationship instances in a set lowers the ri for all those
relationships.
• more relationships => chance of a greater max pmi =>
lowered ri for all relationship instances.
• Not worried → articles likely won't have 200 relations of
the same type.
22. Experiment #3: Extraction on
PubMed Corpus
• PubMed corpus used.
• Want to test the performance of the system on a different
type and sized corpus
• Algorithm was run with input seed relations on this corpus
and10 verbs with the topmost rπ values were extracted
• We constructed a test sentence set of 80 sentences (8
sentences for every relevant verb)
• We then extracted a total of 162 relations from this test set
and calculated their ri scores.
• The average ri score was used as the threshold value
25. Experiment #3 Analysis
• Performance is worse on PubMed corpus.
• Patent corpus dealt with drugs and cures for diseases.
• Therefore, there was an abundance of treatment type
relations in patent corpus.
• PubMed had more general medical data and only
contained abstracts => less info.
• Therefore, there were fewer treatment relations in
PubMed which affected performance.
27. Analysis
• F-score of Ganapathi's version of Espresso fell
nearly 10% → due to lower recall, as predicted.
• Results of extension over the re-tagged data are
on par with Ganapathi's original results.
• When you consider that Ganapathi's system
dropped nearly 10%, it seems to indicate the
increased general purpose nature of the
extension over the original version.
28. Success
• Recall of system is more important than
precision, especially when it comes to using
relationships as a feature in iScore.
• Method is almost completely automated.
• Easily expanded to extract other relationship types by
changing the input seed relations.
• Initial results seem insignificant, but analysis indicates
that extended system has the potential to be a general-
purpose relationship extraction feature.
29. Future Work
• Development of a relationship feature extractor
for iScore.
• Relations will have to be syntactically and
semantically compared with relations present in
other articles and the best article matches will be
returned as “interesting” choices for a user.
• Optimizations: algorithm design
improvements, database connection
optimizations and parallelization.
