Description of interactive freely accessible online quantitative toolkit for linguistic data analysis and visualization. Step-by-step guide how to use this online tool and interpret results.
This document discusses linguistic variation and regional dialects. It defines key concepts like variables, variants, and constraints on variation. Variables are abstract linguistic features that have variants in actual speech. Regional dialects highlight non-linguistic factors on language. Dialectology studies regional variation through mapping speakers and places. Sociolinguistic variables are linguistic features constrained by social factors like education and social status. The document uses examples from British and American English to illustrate variation in spelling, pronunciation, and vocabulary between dialects.
This document discusses sociolinguistic concepts related to language variation, including:
- Varieties include languages, dialects, accents, registers, and styles of a language. Variation occurs at the lexical level through slang and levels of formality.
- Dialects are regional or social varieties of a language characterized by their own phonological, syntactic, and lexical properties. They can also be associated with ethnic groups or socioeconomic classes.
- Registers or styles are varieties of language used in particular social settings defined by levels of formality or social events like baby talk.
- An idiolect is the unique language use of an individual person influenced by various dialects, registers, and languages
This document discusses language variation and varieties. It defines key terms such as language, dialect, and varieties. Some main points:
- No two speakers speak exactly the same way and an individual's speech varies across situations.
- Language varieties refer to different forms of language influenced by social factors like region, social class, individual, and situation.
- A dialect is a language variety spoken by a community that has distinguishing phonological, lexical, and grammatical features.
- Varieties refer to sets of linguistic items associated with external social factors like a geographical area and social group.
- Dialects are influenced by various social factors and everyone speaks at least one dialect. Standard dialects have more prestige than others due

The document discusses criticisms of the generative approach to linguistics, arguing that it provides an overly restrictive view of language that does not account for many linguistic phenomena. It argues for alternative cognitive and construction grammar approaches that view language as framed within human conceptual systems and experience rather than as an autonomous computational module.

Topic : “European linguistic roots: origin, evolution and present situation”.
This study examined the closure of the spheno-occipital synchondrosis (SOS) in 217 Yemeni subjects aged 15-25 using CT scans to determine if it is a useful age estimation tool. The SOS was classified into four stages: open, semi-closed, closed with scar, closed without scar. Mean ages for males were 16, 18.5, 21.32, and 21.78 years respectively, showing a linear correlation between age and closure. For females, mean ages were 15, 20, 21.56, and 20.41 years respectively. Regression analysis generated a formula to predict age from SOS stage for each sex. The study concluded the SOS could be a useful forensic age
Language description and functional GrammarMadiha Batool
Functional grammar analyzes language based on choices and how grammar constructs meaning in context. It looks at analyzing experience, interaction, and message construction. Functional grammar in ESP deals with analyzing processes, participants, circumstances, mood, modality, and clause combining. Notional grammar expresses ideas and social behaviors that do not vary across languages. Functional grammar is useful for ESP as it focuses on actual language use and human thinking. Some advantages are that it provides an inventory of language elements and is based on factual study of language use.

This document discusses the relationship between language and society. It explains that sociolinguistics looks at how social factors influence language use and how language impacts society. It then provides examples of how Indian English has developed its own conventions due to cultural influences. Specific linguistic differences are shown between Hindi/Gujarati and their English translations. The conclusion recommends practicing and listening to the target language for improved proficiency.
This document discusses sociolinguistics and the relationship between language and society. It explains that speech communities share linguistic norms and expectations, and that language varies based on social factors like class, education, age, gender, ethnicity, and style/register. Variations include social dialects, over and covert prestige, as well as differences in formal and informal registers depending on the context and audience.
This document describes different approaches to analyzing and describing language:
1. Classical/Traditional Grammar analyzes the grammatical function of each word based on inflections as in Latin and Greek.
2. Structural Linguistics describes grammar through syntagmatic sentence structures and notions of time, number, gender.
3. Transformational Generative Grammar argues structural descriptions are superficial and do not explain relationships of meaning between surface structures.
4. Language Variation and Register Analysis examines how language varies according to context, such as areas of knowledge in English for Specific Purposes.
5. Functional/Notional Grammar focuses on social functions like advising or describing, and how the human mind thinks in
This document discusses gender differences in language use. It begins by defining sex as biological differences between male and female, while gender describes masculine and feminine social and cultural characteristics. Several studies and linguists are cited that suggest women generally talk more, are more polite and cooperative, while men swear more, talk about sports and machines, and try to dominate conversations. Differences are also noted in topics discussed, use of questions versus statements, eye contact, and intent to connect versus gain status. In conclusion, literature shows clear differences between how men and women communicate, which may be influenced by their differing social roles and upbringings.
The document outlines and compares different approaches to describing language: classical/traditional grammar, structural linguistics, transformational generative grammar, language variation and register analysis, functional/notional grammar, and discourse (rhetorical) analysis. Classical grammar is based on analysis of word roles in sentences but has limited application to English. Structural linguistics describes language through substitution tables and syntagmatic structures, providing a means to sequence language items but failing to explain relationships of meaning.
Language varies based on social factors such as the speaker's situation, social class, education level, age, gender, ethnic background, and geographical area. These social dialects represent the variety of language used by groups defined by different social parameters. Prestige dialects that are valued differ based on whether they have overt prestige recognized by the larger community or covert prestige valued within social communities. Additionally, an individual's idiolect, speech style, and use of linguistic registers vary based on the formality of the situation.
This document summarizes different approaches to language description including classical grammar, structural linguistics, transformational grammar, language variations and register analysis, functional and notional syllabus, and discourse analysis. It discusses how the concept of language variation led to the development of English for Specific Purposes based on register analysis. Examples are provided to show how language varies based on context between informal spoken text versus formal written instructions. The document concludes that developments in language description are interrelated and distinguishing performance from competence is important in describing a language for learning purposes.
The document provides an overview of various linguistic theories and their implications for language teaching, including:
1. Classical/traditional grammar focuses on the role of words in sentences, while structural linguistics describes grammar through sentence structures.
2. Transformational generative grammar examines deep and surface language structures and meanings.
3. Functional/notional approaches analyze language in terms of social functions and intentions rather than form.
4. Discourse analysis looks at language use beyond the sentence level and how meaning is constructed between sentences.
5. Different linguistic theories may be more relevant for describing certain features of specific languages.
This document discusses gender in language from several perspectives. It begins by differentiating the terms "sex" and "gender" in sociolinguistics, noting that "sex" refers to biological distinctions while "gender" refers to social or constructed identities. It then examines the Whorfian hypothesis that language shapes thought using examples of how speakers of languages with grammatical gender describe objects differently based on gender. Several languages, including English, French, Spanish, Icelandic, Norwegian, Swedish, Japanese, and the constructed language Novial are analyzed for their use of gendered pronouns and how they include or distinguish gender.
Regional accents and dialects provide clues about a person's social factors and speech community membership. Two people from the same place may speak differently due to belonging to different social groups. Sociolinguistics investigates language from the perspective of its relationship with culture and role in social organization. Varieties of language use are defined by social factors like class, education, age, sex, and ethnicity. Higher socioeconomic groups use more prestigious forms while lower groups use less prestigious, covertly valued forms. Differences also exist between genders, with females using more prestigious forms than males of the same background.
The document discusses differences in language use between men and women in several areas: minimal response, question asking, turn-taking, changing topics, self-disclosure, verbal aggression, and politeness. Women tend to provide more minimal responses like "mhmm" in conversations. They also ask more questions and are more likely to take turns in discussions. Men typically change topics less and focus more on their own points. Self-disclosure and expressions of emotions also differ between genders.
This document provides an introduction to inferential statistics, including key terms like test statistic, critical value, degrees of freedom, p-value, and significance. It explains that inferential statistics allow inferences to be made about populations based on samples through probability and significance testing. Different levels of measurement are discussed, including nominal, ordinal, and interval data. Common inferential tests like the Mann-Whitney U, Chi-squared, and Wilcoxon T tests are mentioned. The process of conducting inferential tests is outlined, from collecting and analyzing data to comparing test statistics to critical values to determine significance. Type 1 and Type 2 errors in significance testing are also defined.
Here are the key points about pidgins and creoles:
- Pidgins develop as a means of communication between groups that don't share a common language. They are simplified linguistic systems.
- Creoles develop when pidgins are passed down to children and become their native language. Creoles are more fully developed systems compared to pidgins.
- Pidgins borrow features from the languages in contact, like vocabulary and word order. They simplify phonology and morphology.
- Creolization occurs when a pidgin becomes the native language of a community and takes on richer linguistic properties through natural language acquisition by children.
This document discusses inferential statistics, which uses sample data to make inferences about populations. It explains that inferential statistics is based on probability and aims to determine if observed differences between groups are dependable or due to chance. The key purposes of inferential statistics are estimating population parameters from samples and testing hypotheses. It discusses important concepts like sampling distributions, confidence intervals, null hypotheses, levels of significance, type I and type II errors, and choosing appropriate statistical tests.
Language variation and_change_introductionmunsif123
This document provides an introduction and overview of the seminar "Language Variation and Change". It discusses how sociolinguistics examines small language variations that are determined by social factors and can lead to language change over time. These social variations are contrasted with internal linguistic variations. The seminar aims to explain the basic principles of language variation and change/sociolinguistics. Possible topics for student presentations and papers are outlined, covering areas like the history of sociolinguistics, individual case studies, gender differences, and the relationship between sociolinguistics and other fields.
The document discusses the origins and evolution of the concept of communicative competence. It began with Chomsky's distinction between competence and performance. Hymes later argued competence must account for social and cultural factors. He coined the term "communicative competence" to refer to knowledge needed for effective communication. Further researchers like Canale and Swain, and Bachman, expanded on the concept to include grammatical, sociolinguistic, discourse, and strategic competencies. Communicative competence is now understood as the combination of knowledge and abilities required to communicate appropriately in social contexts.
This document discusses various types of language variation including dialects, sociolects, idiolects, registers, pidgins, and creoles. It notes that dialects are varieties of a language used by a particular group that share non-linguistic characteristics. Pidgins develop for communication between groups that don't share a common language, while creoles emerge when a pidgin becomes a community's native language.
Communicative competence involves both linguistic and sociolinguistic rules of language. It has four main components: linguistic competence involving grammar, sociolinguistic competence involving appropriate language use for different contexts, discourse competence involving coherent language structures, and strategic competence involving repairing communication breakdowns. Sociolinguistic competence, involving dialect, register, naturalness and cultural aspects, is particularly difficult for non-native speakers to acquire as it differs across cultures and languages.

Presentation given by US Chief Scientist, Mario Inchiosa, at the June 2013 Hadoop Summit in San Jose, CA.
ABSTRACT: Hadoop is rapidly being adopted as a major platform for storing and managing massive amounts of data, and for computing descriptive and query types of analytics on that data. However, it has a reputation for not being a suitable environment for high performance complex iterative algorithms such as logistic regression, generalized linear models, and decision trees. At Revolution Analytics we think that reputation is unjustified, and in this talk I discuss the approach we have taken to porting our suite of High Performance Analytics algorithms to run natively and efficiently in Hadoop. Our algorithms are written in C++ and R, and are based on a platform that automatically and efficiently parallelizes a broad class of algorithms called Parallel External Memory Algorithms (PEMA’s). This platform abstracts both the inter-process communication layer and the data source layer, so that the algorithms can work in almost any environment in which messages can be passed among processes and with almost any data source. MPI and RPC are two traditional ways to send messages, but messages can also be passed using files, as in Hadoop. I describe how we use the file-based communication choreographed by MapReduce and how we efficiently access data stored in HDFS.
The document discusses an orientation program on data mining using R programming. It covers various topics related to data science including data analysis, data mining, R programming, and basic R commands. Some key points:
- It discusses the differences between data, information, and knowledge. Data is processed to get information, and information combined with experience leads to knowledge.
- The steps in data analysis are explained as collect, clean, organize, explore, and model data to get insights and make decisions.
- The objectives and roles of R programming in data science are discussed. R is a popular language for statistical computing and data analysis.
- Basic R commands for vectors, importing/exporting CSV files, and coercion
This document discusses assessing the quality and coverage of data in the Secure Anonymous Information Linkage (SAIL) databank. It recommends documenting datasets in a flexible way using reproducible research principles. This allows data analysts to import and run SQL and statistics code with minimal training. It also considers publishing reports online and creating interactive web applications using R Studio Shiny to allow querying basic data information through a website.
This document proposes improving the Needleman-Wunsch algorithm for aligning next generation sequencing (NGS) data using Hadoop clusters. It discusses how the algorithm works and the challenges of multiple sequence alignment on large NGS datasets. The solution presented is to implement a parallelized version of Needleman-Wunsch using Hadoop MapReduce to allow pairwise sequence alignment across many nodes, reducing processing time significantly for large inputs. An implementation on a 3-node cluster showed reduced alignment times as input size increased, demonstrating the ability to efficiently handle massive NGS data volumes. Future work could focus on approximation algorithms or further parallelization to improve computational space requirements.
Estimating Species Divergence Times in RevBayes – iEvoBio 2014Tracy Heath
Phylogenetic analyses of macroevolutionary processes require estimates of species divergence times. Critically, this requires a framework for modeling lineage-specific substitution rates and speciation times while accounting for uncertainty in the tree topology. Bayesian inference methods are well suited to such analyses. However, implementations of these methods have historically been limited by the available models and priors in each program. RevBayes is a new statistical programming environment that provides a flexible framework for phylogenetic inference. We have implemented phylogenetic inference under a diverse set of relaxed-clock and branching-process models in RevBayes. The user specifies the model and analysis details in Rev -- an interpreted programming language based on R. I will present the theory behind the implementation of phylogenetic models in RevBayes that gives the software its flexibility and show the results of empirical analyses.
eResearch workflows for studying free and open source software developmentAndrea Wiggins
1. The document discusses using scientific workflows and tools like Taverna for distributed collaborative research on free and open source software development using large datasets, computational resources, and reproducible analysis.
2. Taverna is presented as an example of a scientific workflow tool that allows modular development of analysis through reusable components with input and output ports, offering advantages over scripts.
3. An example workflow is shown that calculates network centralization in dynamic networks and generates time series and CSV output for further analysis.

Scott Laurel has over 10 years of experience as a Database Administrator with expertise in SQL Server, MySQL, PostgreSQL and MongoDB. He has a proven track record of ensuring database stability, performance and high availability. His skills include database design, maintenance, monitoring, tuning, backup/recovery and implementing redundant infrastructure configurations.
Fully featured, commercially supported machine learning suites that can build Decision Trees in Hadoop are few and far between. Addressing this gap, Revolution Analytics recently enhanced its entire scalable analytics suite to run in Hadoop. In this talk, I will explain how our Decision Tree implementation exploits recent research reducing the computational complexity of decision tree estimation, allowing linear scalability with data size and number of nodes. This streaming algorithm processes data in chunks, allowing scaling unconstrained by aggregate cluster memory. The implementation supports both classification and regression and is fully integrated with the R statistical language and the rest of our advanced analytics and machine learning algorithms, as well as our interactive Decision Tree visualizer.

2005-03-17 Air Quality Cluster TechTrackRudolf Husar
The document discusses a federated information system called Dvoy that aims to integrate heterogeneous air quality data from different sources and provide uniform access. It does this through the use of wrappers that encapsulate data sources and mediators implemented as web services that resolve logical heterogeneity and allow for standardized querying of multidimensional data cubes. The system uses mediators and wrappers based on previous research to overcome issues of data access, translation and merging across different source schemas and formats.
The document discusses using a mediator-based architecture and web services to provide uniform access to distributed heterogeneous air quality data sources. Key points include:
- A mediator server can homogenize data coding/formatting from various sources, allowing users to access data through a simple universal interface while minimizing changes to data providers.
- Services like Dvoy use mediators and wrappers to resolve technical and logical heterogeneity across sources and provide multidimensional querying of spatial-temporal data cubes.
- This approach facilitates data sharing and integration for improved analysis to address challenges from secondary pollutants and more participatory management of air quality.

Cognitive executive functions and Opioid Use DisorderOlga Scrivner
This study examined the impact of psychosocial stressors and opioid use disorder on cognitive executive functions in 46 participants with opioid use disorder. The Iowa Gambling Task and Opioid Word Stroop test assessed emotional and logic executive functions. Better social stability and food security were associated with worse cognitive performance, while cannabis use was linked to better performance. Concurrent polysubstance use was also tied to enhanced cognitive function. The small sample size limited conclusions, but food security, cannabis use, and drug stigma warrant further study regarding their influence on executive function.

Reproducible visual analytics of public opioid dataOlga Scrivner
This document summarizes visualizations created to analyze public opioid data in the United States and Indiana. Visualizations show that drug deaths have increased 500% in recent years in both the US and Indiana. Higher opioid prescription rates correlate with more drug deaths in counties over time. While most Indiana counties have at least one substance abuse facility, Indiana has far fewer facilities per capita than neighboring states. Future work is planned to incorporate additional relevant data on topics like pharmacy robberies, needle exchange programs, and doctors prescribing fentanyl.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.
Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

Natural Language Processing (NLP), RAG and its applications .pptxfkyes25
1. In the realm of Natural Language Processing (NLP), knowledge-intensive tasks such as question answering, fact verification, and open-domain dialogue generation require the integration of vast and up-to-date information. Traditional neural models, though powerful, struggle with encoding all necessary knowledge within their parameters, leading to limitations in generalization and scalability. The paper "Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks" introduces RAG (Retrieval-Augmented Generation), a novel framework that synergizes retrieval mechanisms with generative models, enhancing performance by dynamically incorporating external knowledge during inference.
