□Description
In Rakuten, since various big data have been generated, we are using these big data for accelerate our business.
In this slide, I will introduce an approach based on the user behavior analysis such as a product search support system, search keyword analysis.
This document provides an overview of a presentation on big data and data science. It covers:
1. An introduction to key concepts in big data including architecture, Hadoop, sources of data, and definitions.
2. Details on common big data reference architectures from companies like IBM, Oracle, SAP, and open source technologies.
3. A discussion of how data science is disrupting various industries and the characteristics of firms using data science successfully.
4. Descriptions of machine learning techniques like segmentation, forecasting, and the overall reference architecture for machine learning involving data storage, signal extraction, and responding to insights.
Executing successfully a Knowledge Graph initiative in an organization requires a series of strategic decisions that need to be taken before and during the execution.
Issues like how to balance the (inevitable) knowledge quality trade-offs, how to prioritize knowledge evolution, or how to allocate resources between new knowledge delivery and technology improvement, are often not contemplated early or adequately enough, resulting into frictions and sub-optimal results.
In this talk, I describe some key strategic dilemmas that Architects and Executives face when designing and executing Knowledge Graph projects, and discuss potential ways to deal with them.

Transliteration has been usually recognized by spelling-based supervised models. However, a single model cannot deal with mixture of words with different origins, such as “get” in “piaget” and “target”. Li et al. (2007) propose a class transliteration method, which explicitly models the source language origins and switches them to address this issue. In contrast to their model which requires an explicitly tagged training corpus with language origins, Hagiwara and Sekine (2011) have proposed the latent class transliteration model, which models language origins as latent classes and train the transliteration table via the EM algorithm. However, this model, which can be formulated as unigram mixture, is prone to over fitting since it is based on maximum likelihood estimation. We propose a novel latent semantic transliteration model based on Dirichlet mixture, where a Dirichlet mixture prior is introduced to mitigate the over fitting problem. We have shown that the proposed method considerably outperform the conventional transliteration models.

Transliteration, a rich source of proper noun spelling variations, is usually recognized by phonetic- or spelling-based models. However, a single model cannot deal with different words from different language origins, e.g., “get” in “piaget” and “target.” Li et al. (2007) propose a method which explicitly models and classifies the source language origins and switches transliteration models accordingly. This model, however, requires an explicitly tagged training set with language origins. We propose a novel method which models language origins as latent classes. The parameters are learned from a set of transliterated word pairs via the EM algorithm. The experimental results of the transliteration task of Western names to Japanese show that the proposed model can achieve higher accuracy compared to the conventional models without latent classes.

This slide shows an unsupervised method for extracting product attributes and their values from an e-commerce product page. Previously, distant supervision has been applied for this task, but it is not applicable in domains where no reliable knowledge base (KB) is available. Instead, the proposed method automatically creates a KB from tables and itemizations embedded in the product’s pages. This KB is applied to annotate the pages automatically and the annotated corpus is used to train a model for the extraction. Because of the incompleteness of the KB, the annotated corpus is not as accurate as a manually annotated one. Our method tries to filter out sentences that are likely to include problematic annotations based on statistical measures and morpheme patterns induced from the entries in the KB. The experimental results show that the performance of our method achieves an average F score of approximately 58.2 points and that filters can improve the performance.

Purchase prediction by statistical analysis (統計技術を用いた商品購買予測)Rakuten Group, Inc.
This document discusses using statistical analysis of purchase history data to predict users' purchase intervals and remind them when it is time to purchase an item again. It finds that for the rice category, 47% of users have relatively fixed purchase intervals with only a few outliers. By detecting these fixed intervals, a reminder system could notify users just before their next predicted purchase to prevent them from forgetting to buy an item. This has the potential to benefit users while also promoting repeated purchases in various product categories.

Future of shopping - orosy and company -- march 8, 2013, meng meetingGary Orosy
The document discusses how new technologies are transforming shopping into "the toughest race on earth" between customers and retailers. It describes how customers are arming themselves with smart devices and online research abilities, forming new shopping segments based on their interest and value of time. Retailers are responding by collecting and analyzing big data, enhancing store experiences with augmented reality, and exploring new store formats and smart technologies. The document predicts that within a few years, retail stores may exist just for product sampling, with no actual sales, as customers customize and print products at home or have them delivered. The winners will be those retailers that can best cater to the needs of the four emerging customer shopping segments through innovative omnichannel experiences.
The document provides definitions and concepts related to effective category management. It discusses category management as a process of managing categories as strategic business units to deliver customer value and enhance business results. It outlines an eight-step category management process involving category definition, role, assessment, strategy, tactics, implementation, and review. Various category roles are defined including destination, routine, convenience, and seasonal. Category strategies and tactics are also discussed in relation to assortment, pricing, promotion, and display. The document provides examples of mapping categories to roles and linking roles to strategies.
Retailers must choose a retail format that presents their target customers, with considerations including store design, location, products, services, and pricing approach. The format should be ideal for the target demographics. In India, the retail sector was traditionally dominated by small independent stores, but organized multi-outlet retailers are now gaining acceptance and growing rapidly. Various organized retailers are experimenting with different formats, though it is difficult to predict which will be most successful as the Indian market continues to mature. Common retail formats include mom-and-pop stores, specialty stores, department stores, discount stores, convenience stores, hypermarkets, supermarkets, malls, category killers, e-tailers, and vending machines.
This document discusses strategies for marketing in a global environment. It explains that companies must understand local social and cultural elements to succeed overseas. Tailoring products to local needs and becoming part of the local culture helps brands break into new markets while maintaining their authenticity. Successful companies delicately balance local adaptation with preserving their core brand identity. The document provides examples of companies like PepsiCo, L'Oreal, and automakers that have effectively tailored their offerings for different cultures without compromising their brands. Maintaining this balance of local relevance and global consistency is key to marketing successfully on a global scale.
Japanese consumer behavior and expectations differ significantly from Western standards. Some key differences include their preference for quality products and excellent customer service over conspicuous consumption. Younger generations are becoming more individualistic and value-conscious. Japanese also place importance on shopping as a recreational activity due to limited entertainment options. However, consumer habits are changing with people spending less on brands and focusing more on necessity purchases. Retailers must adapt to Japan's aging population, income polarization trends, and evolving consumer lifecycles to succeed in this market.

The document discusses market segmentation, which is the process of dividing a heterogeneous market into homogeneous subgroups. It explains that marketers segment markets based on geographic, demographic, psychographic, and behavioral factors to better understand customer needs and target specific subgroups. The key benefits of segmentation are developing specialized offers for each subgroup and improving marketing efficiency.
Low-end retailers (LERs) like Action, Big Bazar, Extra, Flying Tiger, and Trafic are experiencing significant success and growth in Europe. In Belgium, LERs represent a 1% market share of all fast-moving consumer goods (FMCG), which is equal to the market share of FMCG in e-commerce. LERs appeal to customers through extremely low prices, limited services, and frequently changing product assortments. Their business model focuses on low margins, purchasing large quantities directly from manufacturers to negotiate low prices, and profiting from high store growth and volumes rather than service-based revenue. If LER growth continues, CPG brands and other retailers may need to reconsider pricing, ass

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
